Very funny expressions you've chosen there, Bev.
I imagine Andy is saying "Look out Roger, I'm coming to get you" whilst Federer looks in absolute agony!
I just put in Roger Federer angry and that's what came up. I tried to get something of Andy's match with Tsonga but that's about the best I got facing the right way. I hope that Andy's feeling confident against Rog - he has the game to beat him and he should well remember that.
