Ruben Amorim accepts that finishing chances is the "biggest problem" for Manchester United to rectify after their 1-0 home defeat to Wolves.

Pablo Sarabia's 77th-minute free-kick against the run of play earned Wolves all three points in Sunday's Premier League clash at Old Trafford.

United created a few opportunities, reflected in their expected goals (xG) value of 1.1, but only twice tested stand-in Wolves keeper Dan Bentley.

"If you don't score goals you don't win games," Amorim told BBC Radio 5 Live at full-time. "We need to score goals. 

"There was a time we didn't score, but we didn't create. We had lots chances to score, but didn't – that's the biggest problem for our team," he added. 

United's loss to Wolves was the ninth Premier League game, since records began in 2003-04, to see zero first-half shots from inside the box.

Rasmus Hojlund registered just one shot in 70 minutes on the field as he went a sixth consecutive game without scoring in all competitions.

"We need to continue to work but it is not just Rasmus. The whole team missed a lot of opportunities," said Amorim.

"This season is going to end like this so we need to take the positives and work on what we need to improve."

"We have to look at everything: our squad, what we have to do in the market. We will see," he added.

Amorim has now lost 11 of his 22 Premier League matches with United, which is as many as he suffered across his final 114 league games at Sporting CP.

"We talk every day about next season and with time we will get what we need to improve the team," the United boss said. 

Amorim handed a debut to 20-year-old Tyler Fredricson and also started fellow youngster Harry Amass but it was ultimately a day to forget for the hosts, who are 14th in the league and just two points clear of West Ham United in 17th.

"I think they played really well," Amorim told Sky Sports. "We need to score goals so that the kids have better memories. 

"These days are really disappointing. We were better than the opponents but if you don't score goals, you don't win games."

Sarabia's superb free-kick from 20 yards earned in-form Wolves a first league double over United since the 1979-80 campaign.

Wolves have won five successive top-flight games for the first time since 1970-71 and are now officially safe from the threat of relegation.

"It was not our best match. Technically and tactically, we know that we can play better," Vitor Pereira said. 

"We played with our souls, with our spirit and that is what I saw in the game. The supporters believed and the moment that we had a chance, we scored," the Wolves boss added. 

"We are building something good for the future. We have to go into the next game and believe and with our supporters we can do it."

Wolves host Leicester next weekend whilst United travel to Bournemouth ahead of their Europa League semi-final with Athletic Bilbao.
