Tsonga was crap.
Well I wouldn't say crap exactly, and I think we have to give Federer some credit, but Tsonga was allowing Federer to dictate a lot of the points, at least that I saw.
I wouldn't write Andy off just yet. He knows Federer's game and knows what not to do against him, which I think is just as important as what he should do, if that makes sense. If Andy keeps his wits about him it can be done. If Andy should lose a bit of focus it will be important for him to regroup quickly. I'm not unduly concerned about Andy's physical state, provided he recovers well from today's match.
