Bruno Fernandes insists Manchester United's confidence levels remain high despite the 6-3 defeat to Manchester City at the Etihad on Sunday.
Erik ten Hag blamed part of that defeat to a lack of belief on the day and while Fernandes accepts the thrashing was a setback, he has cautioned against throwing away all the good work.
United had won four successive league games before Sunday, but find themselves 6-1 down at the Etihad before two late goals from Anthony Martial.
