Manchester United midfielder Mason Mount said the club is 100% behind their head coach, Ruben Amorim. The Portuguese manager is under the pump as the team has got off to a mundane start in the Premier League season.

However, some pressure on Amorim was released after United registered a 2-0 win against Sunderland at Old Trafford on Saturday. Mason Mount opened the scoring for the home team, finding the back of the net in the eighth minute of the game. Benjamin Sesko then scored in the 31st minute to give a 2-0 lead to Amorim’s team.

United have now won three in a row at Old Trafford and also secured a first clean sheet of the season.

“We’re 100% behind the gaffer,” Mount told BBC Sport. “We’ve had some results that hurt us – the team, the staff and the fans – but that was important today.

“We thought after Chelsea it would be the start of something and then we go to Brentford and have a disappointing result. It starts today and we’ll be working hard over the break. We want to get back-to-back wins, then three in a row and push on for the top four.”

Amorim called on his players to show that support in the weeks ahead. “I saw today and I know they want to do the best and I know they don’t want to change the coach all the time,” he said, “but, like I said this week, being with the manager is: ‘I will kill myself to do anything in every transition.’ We need to show with actions.

“Sometimes when we look at our team I know for sure that they know sometimes we can do better. We need to show it on the pitch, not just at home, but also abroad.”

Goalkeeper Senne Lemmens made his United debut after his move from Royal Antwerp, and he kept a clean sheet in his maiden appearance.

“He looks confident in the first game,” Amorim said. “But the important thing is that the teammates helped Senne to have a good game because everyone was focused, not a lot of mistakes.”

United will next face defending champions Liverpool at Anfield on Sunday.
