Manchester United defender Jonny Evans says his side's win over Wolverhampton Wanderers piles the pressure on second placed Manchester City ahead of their game with Chelsea.
After playing second fiddle for much of the season, United have a four point lead at the top of the Premier League, with City taking on a rejuvenated Chelea side on Wednesday.
And Evans, who scored his first goal for United at Molineux on Sunday, says the pressure is on for Roberto Mancini's side to react in kind.
"Wednesday is a massive game," said Evans. "We have done our job and that does put pressure on City.
"Chelsea have had a couple of good victories so maybe their spirits will be up a little bit and they will go into Wednesday's game in pretty confident mood."
With City playing twice before United face Fulham next Monday, Mancini's team have the opportunity to reclaim top spot and restore their lead on goal difference, a deficit which was cut to three following Sunday's fixture.
Evans says goal difference could play a huge part come the end of the season, but doesn't want to relinquish the title in those circumstances.
"The goal difference is a massive consideration," he added. "If you look ahead to the end of the season, the last thing you want to do is lose the league on goal difference.
"It is almost like another point at times and it would be a horrible way to lose the league if that was the case, so it is up to us to rectify it."
The Northern Irish defender helped United become the first team to score more than 70 goals in their first 29 games of the Premier League season, surpassing City's goal tally in the process.
