Jose Mourinho is determined to keep his title-winning Chelsea squad together this summer.

The Portuguese tactician admits he wanted to make changes to his playing roster last year but after winning the Premier League with his current group, is looking to develop some of the key players he already has such as Brazilian midfielder Oscar.

Mourinho has high hopes for the 23-year old who he feels has the ability to reach the same level as the competition's Player of the Year Eden Hazard.

"Last year I was keen to see some people leave and our club to raise some funds to buy other players," Mourinho said.

"Fundamental is to keep my players and to try to get the best out of them.

"People like Oscar. Fabulous player. I have a feeling Oscar next year can have the same evolution Hazard had this season."
