Chelsea v Manchester City: Jose Mourinho remains calm but insists Blues must play their own game if they are to win Jose Mourinho knows that his Chelsea side will face arguably their biggest title rivals when they take on Manchester City this Sunday, but he claims to be relaxed about the outcome of the game. The match-up of two of English football's nouveau riche, Oligarch vs Sheikh, is a highly anticipated one - as two of the Premier League's most-expensively assembled squads lock horns. Chelsea come into the game on a seven-match unbeaten run, including 14 goals in their last four games, which sees them with one more point than Man City after eight games. "We have to play our game," Mourinho said. We are going to play our game and let's see if our game is enough to win against them. I just play every game the same way. To win is good, to lose is not good. (But) in this moment, with the way the Premier League is going week after week, no result will put a team in a great situation, no result will put a team in a difficult situation. Every weekend somebody loses points. Some weekends more than one of the top teams lose points. The league is hard, so I don't think at this stage, mid-October, one game is going to be crucial. We have tests every week. It's a big team, yes, it's a very good team, but every match is a test and every match is three points. Yaya Toure, this week the victim of alleged racial abuse by CSKA Moscow fans, promises to be a key figure in the game and Mourinho had nothing but praise for the Ivorian. "Fantastic player," the Portuguese said. He gives them everything. Leadership, defensive work, attacking work, goals, set-plays, physicality, experience. Mourinho was also keen to maintain that Manchester United are still very much title rivals in his mind. "They had lots of difficult matches and other teams, they didn't," Mourinho said. They played already against Chelsea, they played against Liverpool, they played against City. There will come a time and a period of fixtures where they will win consecutive matches and where other teams will lose points and where they will close the gap and where they will put themselves in a position to fight for the title. There was also good news for Chelsea fans in the form of Ashley Cole's return from injury, with Mourinho confirming that Marco van Ginkel was the only long-term injury at the club.
