Don't think he made much difference TBH, Herrera was the momentum swinger. Everton seemed to run out of gas also which helped.
I'm not saying oh Lingard is rubbish bla bla, but when Martial's been in the best form since he first joined why not continue that? He's doing something positive every game so far.
Because the manager doesn't see it that way. Rashford, Lingard etc. offer things that Martial doesn't, the same way Martial offers things they can't. Whoever the manager sees fit will play. It's not the first or last time a manager will prefer certain players. Cast your mind back to the battle between the hardworking Valencia and the inconsistently brilliant Nani under SAF.
Martial will get game time, for now he's doing very well for us when called upon. He was gifted a start against Leicester and apart from a few dribbles didn't look nearly as good as he has been coming off the bench. Movement is a very important attribute for a Mourinho side, something both Rashford and Lingard are streets ahead of Martial in.
We are winning games and thumping opponents, if Jose wins the title preferring Rashford, his decision has ultimately been vindicated. If not, then his decision will be rightly questioned. That being said, I don't think he has a preference for either, he seems very happy to have both options and both have already played a lot of football this season and will continue to do so.
Both Rashford and Martial are top, top talents who offer us very different things. Both will be very important to our hunt for trophies this season, people need to relax. You'd think Martial was demoted to the reserves and hasn't had a sniff of football. He's a young player who's playing very well and is an important part of our squad. As Jose said, he has spoken with Martial on his role this season and Martial obviously is content with it. He will play from the start and sometimes he will start from the bench, that's the benefits of having a very talented squad with depth.
