Ian Ladyman has slammed Manchester United supporters for booing Erik ten Hag when he subbed off Rasmus Hojlund during Saturday's 3-1 defeat to Brighton.
United suffered another damaging result after being thoroughly outclassed by the Seagulls and one moment in particular saw those inside Old Trafford let their frustrations get the better of them.
Just after the hour mark, new £72million signing Hojlund - who had put in a decent performance on his home debut - was replaced by Martial, with the Danish striker only just returning from a back injury that needs to be carefully managed.
