Arteta wants to switch to a 4-3-3 formation next season and is aiming to sign Thomas Partey, Coutinho and Willian. #AFC want to tie down Aubameyang and Emi Martinez to new deals. Club will look to sell some players with Guendouzi available for £40m. : Gunners

The thing is, CFC want to move Willian only because they signed Zyijech. Willian was always good for them, never went missing in big games. Still remember his performance against Barca. There is no decline, still has same pace, technique and vision.
CFC needs to make space for Zyijech, Werner and Havertz. There are also players like Barkley, Mount and Hudson Odoi, who will demand gametime.
Signing Willian for free is a good deal, because he lacks options, and if he wants to stay at London, he will take what we’ll offer.
