Robinho is a luxury item -- high-performance sportscar. City signing him back in 2008 was great from a credibility/PR standpoint for the club's new ownership, but made little sense on the pitch. Despite his hot start, he has proven that he can't be asked or arsed to do the hard work required to raise the club's profile. He's the cherry on top of the sundae that you bring in when all the other pieces are in place, but City tried using their Porsche to plough fields.
City weren't quite Robinho-ready last season. Defensive frailties made it hard to justify putting an attack-only player out on the pitch, and the lack of a creative attacking mid deprived Robinho of the crucial link his game needs around the box.
If City are able to sign Kolarov or a player of similar quality at left back, I think our club might be ready for Robson at long last. That is, if everyone can put the disappointing last 1.5 seasons behind them and give him a fresh start.
