As long as Ronnie delivers, i don't think there will be any problem. Although morale is vital for success, the other players will still respect his footballing abilities despite his actions. Every single player in the squad is bound to have differences in the squad,look at Cole and Sheringham, Ballack and Drogba, Ruud and Ronnie, to name a few. Scholes, Giggs and Gaz have all achieved more but if Ronaldo can continue to be a major force in their success then they will put up with him regardless. Obviously there is a limit to which teammates will endure bolox from other players but in the majority of cases,the overall success of the team will be the defining factor.
