The club have also signed some of their biggest stars from direct rivals.

The Chile international will enter the final year on his contract in the summer and boss has recently revealed that contract talks have been put on hold for the time being.

Arsenal previously sold to in 2012, while Ashley Cole was sold to Chelsea in 2006.

Gunners legend has also echoed the same sentiment as he claimed that Sanchez would be a perfect replacement for the Blues if Eden Hazard leaves for Real Madrid.

“I think Sanchez will leave this summer,” Merson said to Sporting Life.

“I don’t think Arsenal will finish in the top four and if they don’t finish in the top four then I don’t see him staying.”Arsenal Will Definitely Sell Alexis Sanchez This Summer... To Chelsea

“I know the way Arsenal work so there is no way they will let Sanchez leave for nothing if they can get £50 m for him in the summer.

“They will have no qualms in selling him to Chelsea. Arsenal will have no choice – if Chelsea are the team that are prepared to pay £50 m then Arsenal won’t let him see his contract out.”

“People say, ‘Oh well, they won’t sell to Chelsea’, but they sold Robin van Persie to Manchester United so they won’t be fussed about that.”Arsenal Will Definitely Sell Alexis Sanchez This Summer... To Chelsea

“I definitely think Sanchez could be a Chelsea player next season. He is a world-class footballer so he would fit in at Chelsea.”

“People say he is not the same player but he will get you a lot more goals than Hazard. If they can sign Sanchez for £50 m and get £100 m for Hazard then I think that is good business.”

“It is terrible how Arsenal can let a player of that talent [Sanchez] run the years down on his contract,” he said.Arsenal Will Definitely Sell Alexis Sanchez This Summer... To Chelsea

“There’s about eight of the players with contracts running down and I find it extraordinary that they are in this situation.

“Because of everything going on with Arsene Wenger, I think they have just forgotten about the players.”
