Manchester United surprised us all after they announced the mega-money loan signing of Real Madrid target, Radamel Falcao, three months ago.
But, on what was an evening of optimism for Manchester United fans that day, they had to wave off Manchester born Danny Welbeck to seemingly create space for the Colombian. He was a favourite amongst the fans.
A hat-trick in the Champions League, a double in Switzerland on England duty, and on Saturday the only goal in a hard-fought win for the Gunners away at West Brom. He is starting to show just what he can do in the striker position.
It's fair to say the £16million striker wasn't greeted to great belief from the Arsenal faithful, who were hoping the club would have gone out to sign a huge name - even after splashing out on World Cup star, Alexis Sanchez.
It did take a couple of games for him to get going. Arsene Wenger wanted belief from the fans, insisting at the time: "Danny will improve. We don't have to make a problem of that. We have to be patient with him."
Patience is what he got, and now he's beginning to repay it. His statistics this year aren't in the elite bracket. He's only managed to score five goals in all competitions, but to admire a player like Danny Welbeck, you have to look the unmeasurable traits he does have.
Van Gaal believes he does not reach his standards, and that is why he was sold. But to be doing this well after only recently celebrating his 24th birthday, the standard Welbeck can reach is extremely high.
It remains to be seen just how far he can go at the Emirates Stadium, but with the backing of Arsene Wenger - and the Gunners faithful - the sky is the limit for such a hugely talented individual, who might one day come back to haunt his old employers.
