Asked if seeing Federer still competitive makes Agassi think that he could have played more, the former American player himself, interviewed by Marca, said: 'No no. Coming back I would have probably called it a career before.
Every tennis player has a different career and each one has his reason to retire. In my case my body had told me to stop and I didn't have other choice. Also, I never had Roger's game. For me it was easy, but it seems that he can keep going for other four or five years. The only thing I can say is that when the end comes, it comes in a fast way and you do not expect it. Something happens and everything changes.'
