The Spaniard, who has started just nine times in the Premier League this season, reacted angrily to being substituted in the 53rd minute of the Blues' 3-0 win at Southampton on New Year's Day but Mourinho is not looking to offload him in January.
"I want to keep him. I don't want him to go. That is my opinion, my wish, but my door is open," the Chelsea manager said.
"The club's door is open too so when a player wants to speak to us we are there waiting for them.
"If you are asking do you want the club to sell him? I don't want to."
