The way Barcelona played -
David Villa - Messi - Pedro
Rashford - Felix - Greenwood
Martial competes (starts) for the central spot and the LF spot. Sancho comes and competes (starts) either centrally or the right.
Only going to work if we get rid of Sanchez & Lukaku and even Mata & pereira.
Too good to be true though
that's 5 players competing for 3 straight up spots with also the ability to play as traditional CAM for alot of them as well. In an injury tenure even angel Gomes can cover those spots as well as Lingard who should be playing deeper anyway.
See if we play with a diamond formation - the central attacker can join the attack like a false 9 interlinking the inverted forwards whilst the central defensive Midfielder (rice) joins the defense as a false CB. This turns the attack from a front 2 to a front 3 and turns the back 2 in to a back 3 - allowing the wingbacks to go forward too.
