I do think our squad would be more balanced with Savinho rather than Rodrygo.
I think with Haaland, Marmoush, Foden, Cherki, Reijnders and Bobb you have plenty of options who can create and score from more central areas, which is probably Rodrygo's biggest strength. He's not a touchline winger.
Doku and Savinho offer something different in their ability to stretch the game by staying out wide and using their pace 1v1. Yes, they both need to improve their numbers. But I do think that if Savinho can add goals to his game like Vinicius Jr, who couldn't hit a barn door when he arrived at Real, he can be a world beater.
Having said that, I'd only be happy to keep him if he wants to be here. If he's happy to knuckle down, put a smile on his face and work, and justify the faith that Pep and the club have put in him.
