Petrov is not a bad player. His attitude was sulky because hughes was benching him for Robinho despite Robi's glaring lack of effort or form. That being said he lacks the pace he once had and he doesn't enjoy contact due to the knee injury he suffered about a year ago. Some posters have said his road form is lowsy, I would sincerly question that comment as he has shown on a number of occasions the ability to produce on the road even when he is getting only spot substitute opportunities to play. I am so happy we signed Adam Johnson though because (1) he is young, (2) he has ability, (3) he is another player to fill the nationalty quota (4)!!!!! from what I can tell he can use BOTH feet. Petrov's biggest problem I have seen is that he has only one foot, his left. Petrov's left is absolutley deadly both passing and shooting, but I have seen him bungle easy opportunities and shift the ball to his good side or try to outside of the foot one just to avoid using his right foot. This is not acceptable for a starting 11 Top 4 team quality player or for City's needs. He has a role as a left winger and a squad player, he is way to limited by the aforementioned one-footedness to be utilised as an attacking midfielder out of possition. I hope he stays with the team because left sided players are hard to come by especially with his knack for finding players heads with crosses but Adam Johnson is hopefully going to be a more dynamic and versitile player in the next few years. With that in mind I think keeping both of them is important to the squad and I think Petrov's attitude will be more stable under Mancini as Mancini seems to reward merit and effort rather than starpower which is all Petrov every really asked for. I think Petrov had problem being a squad player behind Robinho.
