Not yet. Maybe if Chelsea does bad with him till the summer.
This Roma move should be a temp one till summer and when they sell the club If things go right for them, then they might count on Carlo for the next season. He even said a while back how he'll coach Roma eventually.
Nah, Abramovich will make more significant investments come next season imo. The fact that they signed Torres means he's expecting to build a new Chelsea to dominate in europe.
