Having worked closely with Willian with the Brazilian national team, Edu is perfectly placed to know exactly what our new signing will bring to our squad.
Our technical director is delighted to have signed his compatriot, and says the deal is the first step in "a big process".
"He has a lot of fantastic attributes as a person, as a football player of course, his character," Edu told Arsenal Digital. "I'm 100 per cent sure that everybody in the dressing room, the fans, myself and Mikel will enjoy having Willian in our side.
"We tried to create a better balance in the squad but we know that takes time to balance the squad the way me and Mikel want to. To balance 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. That, for me, is the most important one because I think the squad needed a player like Willian to help them, to be with the guys, helping in all senses. That's why I'm so excited."
