I'd be pretty happy having Raphinha here. He's a very good attacker who has adapted to the Premier League. At 25 he is reaching his peak years, unlike our other younger attackers, who are still developing.
I wonder if he could even adapt to playing as the striker upfront in a fluid 3 man attack. Potentially he could, but I'm basing that on watching some compilations and seeing the positions he gets in.
I really don't see Pepe having a future at the club under Arteta. But it will be difficult to shift him. Hopefully he is the last remnant of our previous transfer regime.
