Juventus is working on two names: Douglas Costa and Angel Di Maria. It should be one of the two for next season's attack. Di Maria isn't an impossible deal to make: contacts have been made as Juventus has shown being able to give important wages (Di Maria earns 9 million euros per season, 7 without his bonuses). Juventus wants to try and should conclude a deal for one of them.
About the goalkeeper, the deal for Szczesny is wrapped up. Arsenal and Juventus have agreed on a 14 million euros deal with 2 more million bonus. The player will get a four year contract with four million euros per season, with a last year augmentation about 4.5 million euros.
