Chelsea manager Roberto Di Matteo has conceded that he will have to reduce the size of his first-team squad ahead of the new season.
One of the players that is said to be likely to depart Stamford Bridge this summer is French midfielder Florent Malouda.
"Florent is back with us now and I will have a talk with him this week," explained Di Matteo. "We cannot name more than 25 players in the squad so we will have to make some decisions.
"Pre-season gives me a great opportunity to look at the new players and see how they develop.
"The final decision on who will go and who will stay will be made at the beginning of August."
According to The Sun, Malouda, Yossi Benayoun and Gael Kakuta will be made available for permanent transfers, while Romelu Lukaku and Kevin de Bruyne will be allowed to leave the club on loan.
