There is always space for through balls, just that no one runs for them anymore since they know xavi or iniesta doesn't pass them. Messi is the only one I see going for the thorugh balls, it's really a bad sign, through balls is a way to counter a parking bus, you see it on real games, they have players running for through balls and after a couple they always score. Xavi and Iniesta need to grow some balls and beginning with the again, hate their "keep the ball" passing, especially when they are losing the game. To win you have to take risks.
