Arsenal chief Edu admits they're working on a major squad clearout.
Edu is aware of the challenge ahead and expects to make sales this summer too, with Mesut Ozil, Henrikh Mkhitaryan, Ainsley Maitland-Niles, Shkodran Mustafi, Mohamed Elneny, Calum Chambers and Matteo Guendouzi all available.
Edu said: “To balance the squad properly, we need to sell players, to buy players and that takes time, not just day and night.
"It will take time but with Willian, we've started a big process. We've identified the needs in the squad and he's the one to start to rebalance the squad as we want to.
"I am really excited and really happy to have a player like Willian because I'm convinced he'll be the one to impact the team straight away."
