NORWICH, United Kingdom - David Moyes backed Danny Welbeck (pictured left) to play a key role in Manchester United's bid to retain the Premier League title after the England striker sealed his side's 1-0 win at Norwich.
Moyes had been unable to pick either Robin van Persie or Wayne Rooney because of injury and initially rested Welbeck on the bench at Carrow Road on Saturday.
But the 23-year-old came on to net the only goal of the game in the 57th minute as United sealed their sixth successive victory in all competitions.
The reigning champions are up to sixth, two points short of a top-four place heading into the new year.
Welbeck outshone Mexico striker Javier Hernandez, who had started, and Moyes was quick to praise his impact.
"If you look at Danny now, he is a big part of Manchester United," Moyes said.
"Obviously his goal made the difference but Danny's performance changed the game.
"We would have started him but he has played a lot of games and 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."
Welbeck's goal, the result of a double deflection of an attempted clearance by Norwich defender Ryan Bennett, was his 10th of the season and his seventh for United.
That already represents a better haul than last season, when he contributed just two goals for his club, but Moyes believes he can become even more deadly in front of goal.
