Sanchez left Arsenal in January 2018 to move to Manchester United, with Henrikh Mkhitaryan going in the opposite direction.
But things did not work out as much as the Chilean could have hoped at United.
Those connected to the Red Devils are expecting the former Barcelona man to leave Old Trafford this summer.
And Lauren, who was a part of Arsenal’s invincible side, said Gunners’ boss, Unai Emery should consider bringing Sanchez back to the club.
“Sanchez is a top player and top players are always welcome at Arsenal,” the former right-back told AmericanGambler.com
“If Emery could get him back mentally, because it has been a while without him playing, then he could be a good addition.
“It depends if he is the kind of player that Unai would enjoy having at Arsenal.”
