M Diarra+Xabi alonso would be incredible (although is seeming less likely as barry has gone to city). However i dont know about M Diarra+Xabi+kaká. Too much going on down the middle and not enough down the wings. In my opinion if you play M Diarra+xabi, you'd want some wingers as opposed to playing with a #10 down the middle.
M Diarra's problem last season (07/08) was that he was given the task of taking the ball from defence to attack. He is a beast in that not many people can tackle him, but his distribution is poor. At lyon he played with juninho and essien. He wasnt asked the distriubite the ball more than a few metres to juninho or essien. Thats why if partnered with xabi (who is one of the best distributers of the ball in the game), im sure they would click.
Pellegrini is a 4-4-2 coach. He always plays with a ball winner (senna, tacchinardi etc), and someone like cani (or sometimes senna if played alongside tacchinardi) to move the ball about. With players like pires and cazorla on the wings. Where would kaká fit into all that?
