|4/11||The Gunners are 4/11 with Bet365 to beat Crystal Palace on Saturday.|
The 26-year-old departed in a £35 million deal to join boyhood club Barcelona in 2011 but stated he would be interested in a return as a coach when he eventually hangs up his boots.
And Wenger has expressed his delight that the player would welcome a return after previously spending eight years in north London under his management.
"I am very happy that a player of his intelligence, technical ability and knowledge of the game would come back one day," Wenger told reporters.
The Spain international also claimed his former side possess "the strength of character" to mount a title challenge and the Arsenal manager hopes both his statements will come to fruition.
He continued: "I hope he is right on the two sides. That he'll come back shows he has kept fond memories of this club."
The Gunners face managerless Crystal Palace in the early kick-off on Saturday.
