What i meant by shaky, is we are having 4 with 3 of them are actually not hard tacklers, not someone like Lass,Sissoko, Fernando, those guys that are suppose to just sit back and do the dirty work. Pirlo is old and to gamble on his fitness for the whole season is a risk. Pazienza, from the likes that i read here in the forum, it looks like he's someone we should keep away instead of a 4th choice. We need a hard man in the midfield, and i see us being linked with Lass even though we are going after Inler. And if we are playing 3 man midfield we definitely need more than 4 in the middle, an injury to one of them can make us go to a game without a CM sub on the bench.
