Yes because Martial has always been a crosser
Rashford & Martial need to play upfront as forwards - forget about crossing; play balls on the floor - not crossing to a lump like Lukaku.
Let Sanchez play behind them as a false 9. Let them all rotate and bring Lukaku on when we need an extra man upfront.
Play them as forwards- if Martial fails as a forward in a team that enables forwards to play together then sell him. I see no use in giving him that much negativity when he is made to play in positions and do things that get the best out of no one.
Him playing on the left wing and Lukaku playing in the centre like Drogba's cousin is not good for him nor martial, nor the CM or AM that plays there. There is a lack of cohesion because Jose has never cared about that - for that reason having a go at individual players is wrong under a manager who has them all playing as individuals.
Next manager & we can have a go at everybody.
