Why Mourinho left Martial out against Crystal Palace

Manchester United manager, Jose Mourinho, has left Anthony Martial out of the squad to face Crystal Palace on Monday, because of an injury, his club confirmed.
Jesse Lingard, who scored the winning goal against Chelsea as a substite last weekend, has taken Martial’s place in the only change for Jose Mourinho.
“Jesse Lingard comes in for Anthony Martial, who is injured,” United tweeted.
The club did not expand on the extent of the 22-year-old’s issues.
Scott McTominay retained his spot in midfield alongside Nemanja Matic and Paul Pogba.
Luke Shaw, Michael Carrick and Eric Bailly were all left on the bench.
Palace will be without Timothy Fosu-Mensah, who can not play against his parent club, but get Martin Kelly and Jeff Schlupp back from injuries.
