Ready to face the challenge: Manchester United head coach Ruben Amorim after embarrassing defeat against Bournemouth

Teenage defender Dean Huijsen opened the scoring in the first half before a penalty from Justin Kluivert and a smart Antoine Semenyo finish in the space of two second-half minutes sealed the three points for Bournemouth.

Sunday's match was a second successive defeat in all competitions, after their 4-3 loss at Tottenham Hotspur in the EFL Cup in midweek.

In nine matches since Amorim started as head coach, Man Utd have won four, lost four and drawn one.

Man Utd were booed off by some fans at the final whistle at Old Trafford on Sunday following a second consecutive home defeat in the Premier League, conceding six goals across those matches.

Worryingly for Man Utd, only Southampton have conceded three or more goals in more Premier League home games this season than United's four.

"I always expected [the job to be tough], especially in these busy months. We are ready to face the challenge," Amorim told BBC Match of the Day.

"We have a lot of situations where they managed to score a little bit similar to Tottenham. It's really hard on everyone in the stadium. We have to fight this moment. "It's a very difficult moment. We have to go again next game."

Man Utd centre-back Lisandro Martinez believes despite results "the team are playing so well" and that everyone in the dressing room is confident they can improve their form.

"I always say in this kind of situation we have to show personality and character," Martinez told BBC Match of the Day.

"We are playing so well and unfortunately, we couldn't score today. We have to believe. At this club, we have to win every game and we know that.

"We are so angry with this kind of situation. We have to work on set-pieces especially. I believe a lot in this team and staff. if they don't score their first goal from set-pieces then it is a totally different game. We missed many chances today. We have to score. We know what we have to do and we have to change quickly.

"We know how big it is at this club. The expectation is very high, it's a process and you can see we are playing so well but we also concede goals and we have to work on that. I know the fans are impatient with us. We are the only ones who can change it.

"It's football and we have to accept it. We are 100% confident that we will get success in this club. It's a process, I don't want to point the finger at one player. We win together, we lose together. It is a big pressure but we love that. I believe a lot in this group."
