Martial and Rashford both have been allocated plenty of game time. It's up to them to kick on and grab their opportunities with both hands. If they don't, it's hardly the managers fault. To be fair to Martial, though, he's done alright when playing in from the left. Sanchez was too good to turn down; unlucky for him, I guess. Now he has to adapt, (or accept less play time), because he's undeniably not at Sanchez' level, and it would be ridiculous to move Sanchez (our best attacker), out of position to accommodate him.
