You honestly believe the situations are the same? Rooney was putting in awful performances for years and still getting picked every week, whereas Martial gets dropped after a great game or a substandard one. Even against Liverpool he was our biggest attacking threat despite having 3 players on him and was the first to be substituted.
At a club like United, players should be picked on merit not reputation.
Martial, at points this season, has been terrible and has fully deserved to get dropped to the bench.
We have 7 players competing for two wide positions so there is no place for passengers.
Martial is a very talented young lad and I'm sure he would have started today had he been fit.
