The Longsight-born striker hit an 81st-minute winner at the Emirates Stadium and admitted that he is keen to extend his run of involvement and burgeoning strike partnership with Wayne Rooney.
“I’m over the moon, but the team worked tirelessly all the way through the game,” Welbeck told MUTV. “It was a great team effort and I think we’re all just delighted to get the three points.
“We worked really hard. A few people were cramping up towards the end – I was one of the victims – but we worked really hard and it was a great team performance overall.
“We had a few chances. We played the ball accurately and made lots of precise passes to get in behind their defence and I think we did really well.
“My aim to come and play for United’s first team and luckily I’m doing that at the moment. To get a starting berth up top with Wazza in behind me, we’re forming a great partnership and I’m just looking forward to carrying that on.”
The 20-year-old revealed that the squad had watched Manchester City’s dramatic victory over Tottenham in the Emirates dressing rooms, but conceded that the champions couldn’t lose focus on the task in hand.
“It was on in the changing room but we couldn’t let it affect us or the way we played – we just played our normal game,” he said. “We just went out there, passed the ball well and thankfully got the two goals and they got just the one.
“Credit to them, they’re a good team and they know how to play football and try and get a goal
