Cape Town - Chelsea manager Jose Mourinho has identified three areas to strengthen his 2014/15 Premier League winning squad.
Teamtalk.com report that Mourinho wants to bring in a striker, a midfielder and a defender during the summer transfer window.
"We have to improve. If we have the same team the other teams will be better than us," Mourinho told reporters.
"The Special One" is also mindful of keeping his squad's best players, saying that his first target is to ensure that Eden Hazard, Nemanja Matic, Branislav Ivanovic, Diego Costa and Cesc Fabregas all remain in blue next season.
Mourinho believes that bringing in new faces will add a competitive dynamic to the squad.
