After a league defeat by Aston Villa, a draw at Notts County in the FA Cup and Wednesday's 2-2 draw at Birmingham, Mancini said: 'I like 1-0s. When you don't concede a goal and you have players like Edin Dzeko, Carlos Tevez or David Silva, you win 90 per cent of the time.

'I prefer now that we are boring for two to three games and we win 1-0.
'At Birmingham we had 25 chances to score, but they scored with the first shot they had. If you watch top teams who win the title they concede few goals. That is what we have to do.'
Since being booed off for so-called negative play in drawing 0-0 at Arsenal on January 5, Mancini's team have conceded 11 goals in six games.

But England goalkeeper Joe Hart is expected to start at Eastlands against West Brom today.
Mancini said: 'Joe for me is the best goalkeeper in England. The problem for me is when the goalkeeper makes a mistake maybe you lose 1-0. If a striker doesn't score it finishes 0-0. I don't think it is Joe Hart's fault. If you look at the Birmingham game we defended very badly at set-pieces. This was the problem, not Joe.
'Maybe sometimes he has lost his concentration but I am very happy with him.'
