NEW YORK - SEPTEMBER 14: Roger Federer of Switzerland returns a shot against Juan Martin Del Potro of Argentina during the Men's Singles final on day fifteen of the 2009 U.S. Open at the USTA Billie Jean King National Tennis Center on September 14, 2009 in the Flushing neighborhood of the Queens borough of New York City.

I am sure this is a question on everyone minds right now.Is it possible for Roger to bounce back at next years U.S Open like he did at this Wimbledon when he regained the crown he lost in an epic match to Rafael Nadal last year?

Or is this the final nail in the confin that the Federer era is well and truly over,because someone other then Nadal has been able to dethrone,and beat him in a Grand Slam final?

Most of you would probably agree that Rogers performance on Monday evening was the worst display of tennis we have seen from him in a Grand Slam final.Over the past year and a half we have seen him decline to an almost unrecognizable player,but somehow he has always been able to dig deep and find his form when it matters the most.Unfortunately this time that was just not the case.When serving for the second set he opened the door for Del Potro to believe he has a real shot at taking the title.That was turning point in the match and I truly believe that if Roger had held serve it would have been too much of an uphill battle for Del Potro to come back from

No point to cry over spilt milk now,the damage has been done and Del Potro proved why he was not only a worthy finalist but a worthy winner too

So the question remains,where does Roger go from here?

This has been a golden year for him,winning the only Grand Slam title that eluded him,as well as winning the grass and clay court slams back to back,breaking Sampras' record but claiming his 15th major,becoming a father of twins and was on the brink of immortality of by setting the bar so high that it would be near impossible for another player to surpass,only to fall at the final hurdle

Of course there is always next year,but lets be realistic now.

It is quite clear that Rogers game now largely depends on him serving well.If he doesn't serve well the Del Potros and Murrays will be all over his second serve.He also largely depends on his first serve/aces to get him out of trouble in his service games.

He can now be beaten from the base line by players like Nadal and Del Potro who arguably have more accurate and dependable forehands as well as backhands.His return of serve is mediocre which is why he finds it hard to convert break points.Serve and volley doesn't easily work against fast movers on the court like Nadal or Murray,and Del Potro proved how he can punish Roger if he came in to try and put pressure on him.This is also the second time that Roger has thrown a Grand Slam final in the 5th set due to mental fatigue.Over and above all of this,it now seems that Roger is not too fussed about losing a match that would have meant he won 3 Grand Slams back to back,each on a different surface and that would have silenced all his critiques

This is truly worrying for any die hard Federer fan

I have no doubt that becoming a father has completely changed his outlook on life and is now probably playing the game for the love rather then the glory,but for a man who has chased victory for so long,is he going to look back at this moment in a few years time with some regret?

Can Roger come back next year and dominate the game,win another U.S Open title,with a healthier match fit Nadal,more confident Del Potro and Murray and all the other players looking to break through?

Or should he start thinking of retiring while he is ahead,cause more losses to those he has a losing head to head record with,will tarnish his legacy?
