Ryan Giggs
Giggs produced a typically brilliant performance to inspire United against Leverkusen.

Manchester United manager David Moyes has talked up the possibility of Ryan Giggs extending his career further after the club's record appearance maker produced a virtuoso performance in helping to secure passage to the Champions League knock-out phase with victory over Bayer Leverkusen.

Antonio Valencia, an own goal from Emir Spahic, Jonny Evans, Chris Smalling and Nani helped the Premier League champions cruise through to the last 16 with victory at the Bay Arena, which saw Wayne Rooney contribute four assists.

And Giggs produced a typically considered performance, laying on the fifth for Nani on the eve of his 40th birthday and despite having edged towards retirement by joining the club's coaching staff in the summer, Moyes isn't expecting the Welshman to call it a day anytime soon.

"People will always question Ryan's age but you can't question him as a footballer," said Moyes after United's 5-0 win.

"He's fantastic. I thought he did brilliantly tonight, in everything he did. He didn't look fatigued; he's a terrific all-round player.

"He is unbelievable. You could even say he is getting better. His vision and pass for the last goal for Nani was superb. And his fitness is also incredible. I am lucky to be working with him.

"The situation with Ryan is he keeps playing and he will tell us when he's had enough or his time is up. He keeps training and playing and his performances have been great."

Giggs joined United's backroom staff in the summer upon Moyes' appointed as successor to Sir Alex Ferguson while the 39 year old will complete his Uefa coaching license next summer.

The move points towards the legendary United winger taking on a senior coaching role at Old Trafford from next season and confirming his retirement at the end of the current campaign. The club are yet to offer Giggs a new contract.

Should Giggs continue into his 25th season as a professional then he would break Edwin van der Sar's record as United's oldest ever player.
