MANCHESTER, England -- Robin van Persie ushered Manchester United into the Champions League quarterfinals -- and potentially saved his managers job -- with a hat trick in a 3-0 victory over Olympiakos that completed one of the competitions greatest comebacks on Wednesday. On one of the memorable European nights at Old Trafford, Van Persie scored three times in a 27-minute span either side of halftime to overturn a 2-0 deficit from the first leg. A slew of brilliant saves by David de Gea were also key to a famous win for the English champions -- and a vital one for their manager, David Moyes. Moyes position had come under intense scrutiny after Uniteds humiliating 3-0 loss to fierce rival Liverpool in the Premier League on Sunday, the latest in a string of dreadful results in his first season in charge. An early exit in Europe could have stretched the patience of fans and Uniteds hierarchy beyond breaking point -- but Moyes is left hoping this can be a watershed moment in his United career. "I dont want to come out here and say this is the moment," Moyes said, "but at the same time, I really hope it is." A nerve-shredding night ended with Olympiakos captain Giannis Maniatis on his knees and in floods of tears, and Moyes saluting home fans and wearing the broadest grin. The under-fire United manager was saved by the goal-scoring qualities of Van Persie, who converted a penalty in the 25th minute, side-footed home his second goal in first-half injury time and curled in a free kick in the 52nd. And he also had words of praise for Ryan Giggs, who at the age of 40 delivered a tireless performance in midfield. Giggs lasted the full match, despite having played only 81 minutes since Jan. 7, and played a crucial role in Van Persies first two goals. "His all-round play was very good," Moyes said. "He defies his age." Van Persie was carried off on a stretcher in the final minutes after hurting his leg in a challenge but Moyes said he didnt think it was a serious injury. Olympiakos slumped to its 12th straight away defeat in England and missed out on securing a place in the last eight for the first time since 1999. The Greek champions had their chances -- some of De Geas saves were breathtaking -- but defensively they were chaotic and they became only the sixth team to squander a two-goal lead from the first leg of a Champions League match. "We were unlucky," Olympiakos midfielder David Fuster said, "and were pretty upset about it." In Wednesdays other last-16 match, Borussia Dortmund advanced 5-4 on aggregate despite losing the second leg 2-1 at home to Zenit St. Petersburg. The draw for the quarterfinals is held on Friday. "We probably now will go into it as underdogs," Moyes said. "If we play to our capabilities, which we have not done too often, then I think we will be a match for any team." Moyes insisted on the eve of the biggest game of his reign that his position was not under threat, saying Uniteds vision was "long term," the board was still supportive and stressing that he was in a six-year contract. Fans appeared to be starting to waver, although the banner reading "The Chosen One" -- a nickname given to Moyes after he was hand-picked for the job by predecessor Alex Ferguson -- remained hung up high in the Stretford End as Olympiakos kicked off. Initially, United was gripped by panic -- misplacing passes, diving into tackles and showing no shape defensively -- but the nerves were settled by Van Persies penalty. The Netherlands striker tumbled after being barged in the back by Jose Holebas after bringing down a cross-field pass from Giggs, and he got up to convert his penalty unerringly. Giggs was the architect of the second goal, too, floating another pass to Wayne Rooney, who crossed for Van Persie to caress his finish under goalkeeper Robertos dive. The aggregate score was now 2-2 and Moyes greeted the goal with repeated fist-pumps and marched back to the dressing rooms, breaking into a jog at one point. He was celebrating again within six minutes of the second half when Van Persie curled home a free kick from just outside the area, with Roberto earning the wrath of his defenders for not trusting his wall and vacating the area near where the ball crossed the line. With Olympiakos attacking relentlessly in the final 25 minutes, the final whistle was met with relief as much as joy by home fans. Languishing in seventh place in the Premier League, the Champions League remains a potential source of silverware for United this season. Hydro Flask Standard Mouth Sverige .

Washington Redskins coach Jay Gruden made it all but official Thursday when he said he has every intent of starting Robert Griffin III against the Minnesota Vikings.All systems look like theyre go, Gruden said.Gruden said Griffin is fully recovered from a dislocated left ankle suffered in Week 2 and that the third-year quarterback took most of the first-team snaps in practice ahead of Colt McCoy, who started Monday nights upset over the Dallas Cowboys.We feel hes at 100 per cent physically right now, Gruden said. But we still have another day left and to make sure thats the case. All the doctors are on board, the trainers are on board, as far as physically, he looks great.Gruden again said he wants to make sure Griffin is comfortable running the playbook, including all the new plays and concepts added over the last six weeks.I want to see him decisive with the ball, throwing the ball, accuracy, feet in the pocket — very important — make sure hes not jittery, make sure hes not tentative whatsoever with his reads, his decisions, Gruden said. Make sure hes confident, plays with that confident air that he has that everybody loves moving forward, and (then) well make the final decision, but everything looks good so far.The Redskins did not make Griffin available for comment. He is scheduled to address reporters on Friday.Starting Griffin over McCoy has its risks in the Redskins quest to climb out of their early-season hole. Griffins only game in Grudens system, which is geared toward making Griffin less of a running quarterback and more of a pocket-passer, was a far-from-inspiring 17-6 loss to the Houston Texans in Week 1.McCoy, meanwhile, has completed 36 of 42 passes in 1 1/2 games since Kirk Cousins was benched at halftime against the Tennessee Titans and has the Redskins (3-5) on their first winning streak since 2012. The more experienced hand of McCoy could arguably fare better against the complex defensive schemes run by Vikings head coach Mike Zimmer.But Griffin remains the key to Washingtons futurre, and the team needs to see if he can remain healthy after three major leg injuries over six college and NFL seasons, while also determining whether he can develop the all-around game expected of elite quarterbacks.dddddddddddd Griffin is currently under contract through 2015, and the Redskins next spring will have to decide whether to exercise a team option for 2016.Hes played five quarters of football as a starting quarterback for me since Ive been here, Gruden said, and hes got a lot to prove.Gruden said he wont limit Griffins mobility with play-calls because of the injury. Griffins best moves — including bootlegs and the read-option — will be part of the game plan.We cant hold back because of any past injuries, Gruden said. Hes got to play the position the way he plays it.Griffins return changes the viewpoint from the Vikings defence. In two games vs. Minnesota, he is 41 for 59 for 463 yards, four touchdowns and one interception, along with 20 rushes for 182 yards and two TDs.Youve got to treat him like an extra running back, Vikings defensive end Everson Griffen said. Weve just got to hit him.The Redskins have a bye following the Minnesota game, but Gruden said there was no reason to keep Griffin waiting any longer. The quarterback wouldnt gain much practice time during the extra week because teams are mandated to give players at least five days off.Theres really no benefit to, if hes healthy, to really sitting him and waiting for the bye because its not like his leg is going to get stronger, Gruden said. His legs fine, so, (what) the heck.The nonstop barrage of RG3 questions was perhaps taking its toll on the first-year coach, but he handled it with humour. Asked if he could just go ahead and declare once and for all that Griffin is starting, Gruden replied: We have every intent of him of him starting, but, you know, (shoot), who knows?After some laughter, he added: I might just change my mind now and just start Colt for the first play of the game — just to tick everybody off.___AP Pro Football Writer Dave Campbell in Eden Prairie, Minn., contributed to this report.___AP NFL websites: www.pro32.ap.org and www.twitter.com/AP_NFL___Follow Joseph White on Twitter: http://twitter.com/JGWhiteAP ' ' '
