Manager Jose Mourinho insists goalkeeper Petr Cech will be at Chelsea next season.
The 32-year-old was expected to start against Liverpool on Sunday but was ruled out with a minor injury with Thibaut Courtois taking over in goal.
The Portuguese also spoke about his project ahead of next summer's transfer window.
"With [Kurt] Zouma it's something in his knee, it's a pity because even though he played many matches already, it was important for him to play these last matches and get more Premier League experience," Mourinho said after the 1-1 draw.
"[Petr] Cech's is a small injury but we don't want players to end the season with problems.
"Against West Brom if he is fine he plays, but he plays because he deserves it, not because it's goodbye. I still believe next season he will be with us. He was supposed to play today, he knew that.
"[Transfers?] The first thing I want is to keep my players and I think we will do that.
"Last year I was keen to see some people leave and for the club to raise funds. This season I'm so happy with what my team gave me that what's fundamental is to keep my players and try to get the best out of them.
"Someone like Oscar, for example, is a fabulous player but he's never had a pre-season in his life. He's always been playing in tournaments everywhere, he's never had a rest.
"Now, because he's injured he's not going to the Copa America and I have a feeling that next year Oscar can have the same kind of evolution as Hazard had this season.
"I'm happy with my squad and I have to respect the people that gave us the title."
