Jose knows the value of a 1v1 specialist who can score. He'll also know Martial has given Clyne problems before. In a game where we'll be looking to isolate our forwards 1v1 Jose will have to include the team's best player in that department. And having got his season up and running today, his confidence will be on the up etcWorst thing is, I don't think he will start vs Liverpool. Jose will start Lingard because he runs round a lot.
Lingard may play, but not at the expense of Martial.
