Hmm...I honestly love Kaka. He is such a great role model. However, i believe he is inconsistent. I noticed in the preseasons that he had some games in which he was extremely good - quick with the ball, had good control and provided very good assists - but other games he was just lacking in ability.

I think his age and injury prone-ness has got the better of him. It pains me to say it but i think it would be better for his career to leave. He is not in Mourinho's first team plans. But all that said, he is needed as a back up in case Ozil gets injured or something. That is why i think he should stay.
