Arsenal technical director Edu is looking to add two more signings to Mike Arteta’s squad after finally securing a deal for Willian.
The 32-year-old was a free agent after leaving Chelsea, having spent seven years at Stamford Bridge.
Willian had rejected the offer of a two-year extension with the Blues, paving the way for him to join their London rivals for three years on Friday.
And now, according to the Daily Star, the Gunners will step up their efforts to sign Atletico Madrid star Thomas Partey, as well as a new defender.
The north Londoners want Ghana midfielder Partey but will not pay his £45m release clause, and are attempting to bring the price down.
And they’re also struggling in their pursuit to bolster their defensive ranks, with No.1 target Gabriel Magalhaes expected to join Napoli from Lille.
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.”
Meanwhile Willian believes Mikel Arteta can turn Arsenal back into Premier League title contenders.
“I decided to join the club because Arsenal is one of the biggest clubs in the world, and because of the new project with Arteta,” said Willian, who will wear the number 12 shirt at Arsenal.
“I think this club deserves to shine again, and I want to be a part of this project.
