Jack Wilshere believes that when played in the right position Danny Welbeck will shine for Arsenal, insisting that the youngster will hit his peak under Arsene Wenger.
While some have expressed shock that Manchester United would let Welbeck go to a rival on deadline day Louis van Gaal told reporters that he simply didn't score enough goals to be a striker of the club's calibre as they welcomed Radamel Falcao to Old Trafford.
But Wilshere believes that Wenger will get more out of Welbeck than Sir Alex Ferguson or David Moyes ever could and United could go on to regret their decision to sell him to Arsenal.
"He's never really had that opportunity to play up front, even for England it was only because Daniel Sturridge was injured that he got that chance," he explained, according to the Mirror. "He went into the game with a point to prove and he did that.
"I think his best position is through the middle, he can play on the wings as well as we've seen for Manchester United in the past few years.
"With his pace and his work rate he can get up and down and cause the defence problems from inside or outside.
"His best position overall though is through the middle, as you saw with England in midweek, once he gets in front of goal, he can really punish you.
"He can improve with training, working with different players and different ways of coaching. The manager can get the best out of young players."
Wilshere also revealed he was concerned Welbeck might go to Tottenham, and nagged him to sign for Arsenal as soon as he knew the Gunners might be interested in the England international.
"It was a bit of a strange one because I was going to training and remember reading that Tottenham were interested," he explained. "I thought it was a bit strange that we weren't interested.
"As soon as we got to the training ground he said to me that there was a chance it might happen. From then I was on to him every five or ten minutes asking: 'is it done, is it done?'
"It was not done until 11.30pm and we were all buzzing because he's a great addition.
He added: "I'm not sure it will come back to bite them because they've got Falcao in but for me Danny is a Manchester boy, born and bred in Manchester, so it was a strange thing to see him go.
"It's great for Arsenal and for £16m in today's market that's a bargain. You never know in the future it might come back to haunt them.
"You saw for England what he can do at the very top level playing for his country. He showed under pressure in front of goal he keeps his calm."
