I mean he isnt as old as Schevchenko, and crazier things have happened
It's not really due to age though. Problem with Torres is he fucked up his knees, which is a bad for footballers. Look at the state Kaka has been in. He didn't just move to Madrid and lose it. He had knee surgery and it fucked him over, just like it has to Torres. Before Shevchenko moved to us, what did injury did he have? Knee ligament damage.
It's worse for Torres, because it's taken away his pace, which was his biggest attribute. That's something that doesn't come back.
The best thing he can do is as I said, develop a poacher sense, so that he can still score goals, because he isn't going to be putpacing defenders anymore.
