Manchester City boss Roberto Mancini played down injury fears over Yaya Toure following Monday's 2-1 friendly win over the Vancouver Whitecaps.[LNB] Toure turned his ankle towards the end of the first half and it quickly became apparent that the Ivorian would not be able to continue.[LNB]Toure had to be helped back to the City dressing room and played no further part in the game.[LNB]The injury initially looked serious, but Mancini insisted that the damage was not too bad.[LNB]"We will have to see but I hope he will have recovered in three or four days," the Italian said.[LNB]"He fell over the other player's foot and hurt his ankle, but hopefully he will be OK."[LNB]Mancini will be a relieved man if the initial assessment proves to be correct given Toure's importance to the City cause.[LNB]In addition, even as Carlos Tevez is preparing for a new phase in his career, a new striker was emerging in John Guidetti, who equalised for City before Shaun Wright-Phillips slammed home a late winner.[LNB]"John is young. He is a good player and I think he can have a good future at Manchester City," Mancini added.[LNB]"He is strong. He is a typical English striker, even though he is Swedish. He has a good technique. He wants to improve.[LNB]"He will have time here. It is important that he continues to work well and continues to improve.[LNB]"Today he scored a good goal but when you are a young player, you need to improve every day. This year is important. He has a chance."
