Chelsea boss Jose Mourinho says he's not interested in what happened in the summer between Arsenal and midfielder Cesc Fabregas.
The Gunners opted not to activate the contract's buy-back clause with the 27-year-old instead signing for Chelsea.
"I don't think that's important," Mourinho said on Arsenal opting not to buy Fabregas back.
"For me he is a Chelsea player and he has been phenomenal for us.
"He has responsibilities and the fact the team is playing well and getting results, I couldn't be happier with the moment we decided to bring him to the club.
"I don't know if Chelsea was his first choice and I'm not even interested in that. For me, he is just one of my players."
The Spaniard is expected to receive a cold welcome by the travelling Arsenal fans at Stamford Bridge but Mourinho believes they will be silenced by the home crowd.
"The reaction from Arsenal fans - nobody listens," said Mourinho.
"If 40,000 Chelsea fans want, nobody will listen to what 3,000 in red do.
"I think the feeling should be a good one between him and Arsenal supporters."
