Yes. I always remember how Xavi was always offering himself to every teammate (when some of our players, NOT Xavi, had the ball) when he was a Dmc and a Mc. Xavi was always somewhere near, and available for you to make an easy pass to him.
Masch, on the other hand, zero, nothing.
I have said on chat that he sometimes just stands back and watches our action, in a Gk's mode.
Sit back, not doing any move/support/help for Xavi+Iniesta.
Masch could be the best tackler in the world, or whatever, but he is just very, very poor in some other duties from a defensive midfielder, especially for Barca's level.
But... didn't you watch the world cup? /sarcasm
Busquets being injured at this time could be as bad for us as Valdes getting injured and forcing us to rely on Pinto in our most crucial games of the season. For all the hpye Masche has behind him he's really nowhere near Barca CDM standards.
