Manchester City boss Roberto Mancini admitted the win over Wigan was more important than the performance as his side moved three points clear at the top of the table.
Edin Dzeko's first-half header was enough to see City overcome bottom of the table Wigan and restore City's lead at the summit.
City made hard work of the win with Joe Hart producing a fine save from James McCarthy to secure the victory for the visitors.
Mancini was happy to win ugly emphasising all that mattered was the three points for City.
"It was about the victory not the performance tonight," Mancini told Sky Sports HD1.
"It was really important to win tonight. We knew that was difficult because Wigan this month have played very well and Roberto Martinez is a fantastic manager.
"At this moment we have a lot of players injured, we have a big problem and for this reason it is not important maybe to play very, very well, but important to do a good result.
"I was nervous when it was still 1-0 but that's normal, every player and manager is nervous."
Mancini refused to comment on referee Martin Atkinson after he only booked Maynor Figueroa for deliberate handball late on to deny Sergio Aguero a clear run on goal.
Mancini appeared to wave an imaginary card at Atkinson following the incident, but the Italian refused to get involved the controversy after the game.
"I don't want to talk about the referee and that situation," added Mancini.
Mancini hopes Dzeko can build on the goal after ending his 11-game streak without a goal.
"I'm very happy for him because he deserved to score a goal," continued Mancini.
"He scored this very important goal for us and I hope he continues it in the next game."
Next up for City is third-placed Tottenham and Mancini is expecting an exciting encounter with Harry Redknapp's men.
"It is a big game because Tottenham are doing a fantastic season," noted Mancini. "They are a big team and it will be a fantastic match on Sunday."
