Couple of things, firstly, completely agree on Bobb. Before his injury he looked like a difference maker but since it he's looked like a right wing Grealish. Too much turning inside and making the safe pass. There's enough talent to persist a bit longer but he's gone from potentially nailing down that spot to looking like a player for cup games.
Second, as for Marmoush, I agree he's not a winger but the formation Pep seems to be favouring at the minute doesn't require an out and out winger. The positions Cherki and Doku seem to be receiving the ball in is inside the pitch rather than out on the touchline. Its just wide of where a 10 would be and its the sort of spaces that Marmoush could be lethal with his long range shooting. I'd love to see him given a chance there. Nothing against Cherki as he'd done well but I'd like to see him compete more with Foden for the 10 spot which will give him even more creative freeedom
