Manchester United defender Jonny Evans believes that Chelsea have a good chance of causing an upset against Manchester City this week.
The Red Devils sit four points clear of their North West rivals at the top of the Premier League table with Man City due to face Chelsea, who are heading into the clash on the back of a four-game winning streak.
"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."
The league title could be decided on April 30 when United and City meet at the Etihad Stadium.
