He should be the first offensive sub from now on. Bench Coutinho, play Dembele in the starting line-up. Malcom generates chances, gets stuck in challenges as well. A more tenacious and energetic player than Coutinho by a large margin, and that is what is needed from the third forward playing with lazy players like a tired Suarez and Leo.
Players of his age and potential would want more than just being bench players. And I'm not sure he is good enough to ever be a starter at Barcelona with Dembele also on his position.
Malcom: "It will be hard to be in the starting XI because we have the best players in the world but I will keep working hard to be the 14th or 15th player."
idk, by his words it seems like he is a genuine Barca fan and wants to succeed here, even as a sub impact player. I think it's great to have someone like him.
