Former Manchester United striker Louis Saha feels manager Erik ten Hag is losing the fans' support.
Saha says Ten Hag must recognise he's making in-match errors.
"The feeling is definitely that the supporters are losing hope in United. The supporters expect the team to fight. We didn't see the energy and aggressiveness required in the derby. The responsibility falls on the coach," he told the Evening Standard, referring to Sunday's derby defeat to Manchester City.
"The players must understand that it is not good enough. Ten Hag must be brave, but also realise his own mistakes and correct them.
"His decisions are influencing and he made some mistakes against City. He should be criticised for that."
