Norwich 0-1 Man Utd: David Moyes says Danny Welbeck made the difference

Manchester United manager David Moyes wants striker Danny Welbeck to work on his finishing - despite watching him score the winner at Norwich City.

Welbeck, 23, came on as a half-time substitute before scoring his fourth goal in five games to secure a sixth straight win for the Red Devils.

"If you look at Danny now, he is a big part of Manchester United," said Moyes.

"His performance changed the game. He's a really good player. What he needs to become now is a really good finisher."

Despite a fortunate double-deflection creating Welbeck's chance just before the hour mark, the England international still had to keep a cool head.

But he confidently rounded goalkeeper John Ruddy to slot home.

"We would have started him, but he has played a lot of games," said Moyes of his decision to leave Welbeck out of his starting line-up.

"We are trying to make sure that we give the squad the right opportunities to play and make sure we give them chances to show what they can do.

"Danny has been playing very well and came on to make the difference."

Up until the goal, United had struggled to cope without striker Wayne Rooney, who inspired United's comeback win over Hull on Boxing Day but missed the trip to Carrow Road with a groin injury.

The 28-year-old is expected to be fit to face Tottenham on New Year's Day, however, and Moyes is also hopeful that Robin van Persie will soon return from a thigh injury.

"I would expect Rooney to be back for Wednesday, but he has got an adductor injury in his groin which kept him out of the Stoke game [in the League Cup on 18 December]," said Moyes.

"Ideally we would like to give it a bit longer than three of four days between each game, but we are not getting much time at this point of the season.

"Robin has started some light training and he might not be too far away as well.

"We have not had them as a partnership very often, and we are looking forward to having them together."

The victory over Norwich put United sixth in the Premier League, two points off the top four and seven points behind leaders Manchester City.

However, their position could change depending on Sunday's matches and Moyes is refusing to get carried away by his side's improved form.

"To win two away from home over Christmas takes a lot of doing we have had a few injuries and a lot of our key players out," he added.

"I am delighted with how we are doing and want to keep it going, but I don't think it is anything to shout about."
