Henrikh Mkhitaryan will move to Arsenal in a swap deal for Alexis Sanchez
United’s contract offer will see Sanchez rise to the top of the Premier League wages table.
The Red Devils are one of the biggest spenders on wages in the world.
Arsenal, meanwhile, have tried to stick to a wage structure even though it has led to the contract stand-off with Sanchez and his team-mate Mesut Ozil.
Wenger said of the contract offer to Sanchez: “We did the maximum we could afford to do, maybe one day I will come out with the numbers on that.”
