Chelsea manager Jose Mourinho says goalkeeper Thibaut Courtois will make his long-awaited comeback from injury this weekend against Bournemouth.
The Belgium international suffered a knee injury in September that kept him out of action for almost three months.
Defender John Terry, midfielder Ramires and striker Falcao are still ruled out.
"I was hoping everybody would be fit but it's not possible," Mourinho said.
"John [Terry], Ramires and Falcao are still out. [Thibaut] Courtois is selected. I haven't told them who is starting, they must be the ones to know but he is selected in the group.
"I have to make a decision but clearly sooner or later he will be number one, so if he doesn't play against Bournemouth he will play against Porto.
'He was our goalkeeper all last season and we know how fundamental he was for us so it's very important we have him back.
'To lose your number one for three months, something like 19 matches in all competitions without the best goalkeeper in the world, was hard for us. It's been a long, long time, too long, but now we feel better.
'We have him, we have [Asmir] Begovic, [Marco] Amelia and [Jamal] Blackman and now we are safe. We are again in a super position where we have the best and a very good one."
