Manchester City boss Roberto Mancini wants full commitment from his player's if they intend to improve on their second place standing in the Premier League. City lost to Wolves at Molineux in October and the struggling Midlanders also recently beat Chelsea.
He said: "If you beat all these teams; the ones like Wolves, Blackpool and Aston Villa and draw against those like Chelsea and United, you win the title.
"But it is not easy.
"The problem comes when you meet a team that, in your head, you think are easy.
"Against Arsenal, United or Chelsea, you don't need to remind yourself to concentrate. You are there a week before.
"But if you think a game is going to be easy, that is when you lose. It happens here and in Italy. In 2011, there is no such thing as an easy game."
Mancini wants more than 110%, he wants 200% effort from his charges.
"Why did Chelsea lose against Wolves recently? Because Wolves ran for 95 minutes and fought for every ball. For them it was the game of the year. It is something we must understand." the Italian continued.
"Maybe against Leicester on Sunday, we thought it was easy.
"Yesterday, Arsenal lost against Ipswich. In the FA Cup, Newcastle lost against Stevenage, Derby lost against Crawley.
"These results do not happen in Italy. Here, every game is very strange. If you don't play at 200%, you are at risk."
With United not playing at Tottenham until Sunday, City will go top with a win, but Mancini is not thinking that far ahead.
He added: "We should not think about it. We should only think about our games.
"The season is very long and we have another 17 matches to play.
"The table could change every three days, so we must focus only on Wolverhampton, nothing else."
