Chelsea manager Jose Mourinho happy with Roman Abramovich relationship

Jose Mourinho has told Sky Sports News he is happy with his professional relationship with club owner Roman Abramovich as he prepares to begin Chelsea's defence of the Premier League title.

Mourinho -- whose first spell at the club saw him win two league titles before leaving in 2007 -- said he and Abramovich had "a bit of a disagreement with some ideas."

But he returned to Stamford Bridge two seasons ago and captured his third title with the Londoners last season.

"In my first period, my personal relationship [with Abramovich] was very good... professionally, we had some interferences and a bit of a disagreement with some ideas," Mourinho explained.

"At this moment, we don't have this problem."

The Portuguese said Abramovich had asked him to "fight for titles" and added: "In my first season we were almost there, in my second season we did it and in my third season... if you are close, you can always do it."

He predicted that the Blues would come under pressure from Manchester City, Manchester United, Arsenal and Liverpool in the title race.

"Arsenal are a fantastic club with great players," he said. "Liverpool have amazing investment.

"Man City is a squad to love and a club, with two Premier Leagues in the last four or five years. And Man United with everything -- the history, the players, the investment."

Chelsea face Swansea at Stamford Bridge on Saturday, with Mourinho looking for a quick response to their 1-0 Community Shield defeat to Arsenal at Wembley last weekend.
