Mancini tells Man City players to forget Man Utd
As they close in on a first cup final appearance since 1981 and given the opposition standing in their way, there is little doubt most Blues fans would trade elimination at the Riverside to guarantee victory over Sir Alex Ferguson's team.
But Mancini accepts life does not work that way, which is why his players remain focused on the task in hand.
"I have told the players they should not be thinking about the semi-final," said the Italian.
"We must have full attention on the FA Cup. We can prepare for the next game as soon as the final whistle goes.
"I will not be thinking about the match against United next week just what is best for the team and the players.
"I will play the strongest team I can at Middlesbrough but we do have a lot of injuries."
