Manchester City's second-choice keeper Shay Given will discover this week if he needs to undergo surgery after suffering a shoulder injury.Given, who has largely been back-up to Joe Hart this season, did not make the bench for Sunday's 5-0 FA Cup fourth-round replay win over Notts County. [LNB]"He will go to the doctor in London to see if he needs surgery," said City manager Roberto Mancini after the game. [LNB]Republic of Ireland keeper Given has played four times for City this term. [LNB]Third-choice keeper Stuart Taylor was on the bench for the visit of Notts County as City eventually swept aside the League One side to book a fifth-round encounter with Aston Villa on 2 March. [LNB]Looking to deliver City their first major trophy since 1976, Mancini stressed that he was encouraged by the way his side stuck to their task after a difficult first half-hour. [LNB]"We started the game so slowly because when you play every three days it is difficult to play 100% in every match," admitted Mancini, who felt the club's Europa League draw with Aris Salonika in Greece on Tuesday affected his players energy. [LNB]"It was an important win. For us it [the FA Cup] is important. [LNB]"After we scored, it changed the game. We had more chances in the second half and it was important we scored those goals. [LNB]"Patrick [Viera] played well, he scored two goals and I am happy for him as I am for [Edin] Dzeko, because it is important for strikers to score. [LNB]"Dzeko had three or four chances to score. But I think Edin needs time as all players who play for the first time in England need time."[LNB] This is the world's wealthiest team and we've matched them for an hour. A 5-0 score doesn't justify how well we played Notts County boss Paul Ince Notts County boss Paul Ince felt his side were unlucky not to be ahead before City scored but admitted that they needed to take their opportunities to have a chance of beating their Premier League opponents. [LNB]"We did ever so well and with a bit of luck we could have been 1-0 in front," said the former Manchester United midfielder. [LNB]"That is what you need when you come to places like this. We started well and at times it felt like a home game. [LNB]"We were ready for it but when you get your chances you need to take advantage and but for the width of a post it didn't happen. That would have set us off nicely. [LNB]"I'm disappointed for the players. [LNB]"This is the world's wealthiest team and we've matched them for an hour. A score of 5-0 doesn't justify how well we played as a team."
