Cesc Fabregas is returning to the Emirates Stadium on Sunday and Arsene Wenger hopes Gunners supporters will give him a good welcome.
The Chelsea midfielder had a prolific spell in north London before moving to Barcelona in 2011 for £47.5 million, and after four years, he is making his first return to the Emirates.
Arsenal manager Wenger said: “I want every player to be respected, and Cesc Fabregas, when he comes to the Emirates on Sunday, should be respected like he deserves.”
He even added: “The regret I have is that he wanted to leave here.”
Since moving from Barcelona to the Blues last summer, Fabregas has made a big impact in a Chelsea side set to claim their first Premier League title since 2010.
But it was at Arsenal where the 27-year old Spaniard made his name, making 299 appearances at the club and scoring 56 goals in the process. He moved to Chelsea after making over 150 appearances for Barca, and is a regular starter under Jose Mourinho.
