In the current offseason Chelsea managed to strengthen the defender of Roma Antonio Rudiger, Monaco midfielder Tемуmoue Bakayoko and Real Madrid striker Alvaro Morata.
In the next season, the team will not help the two most important players, who played a big role in last year's success of the "blue" - midfielder Nemanja Matic and striker Diego Costa.
According to head coach Chelsea Antonio Conte, Londoners need new players in order to defend the champion title.
"Undoubtedly, we need transfers," the Italian said in an interview with Sky Sports.
"This is a difficult league. Six teams are very strong, and we must be prepared. I hope we will have the opportunity to improve the composition. The transfer window is still open ".
"We want to be competitive and re-compete for the title. The club knows my goals ".
"It will not be easy. Defending the title is a huge test for us, but we will try to do it. We are working hard on this, "- said Antonio.
Earlier, the former defender of Liverpool Jamie Carragher suggested that the next season will be the last for Conte in Chelsea.
