Tottenham Hotspur have finally got their act together on the pitch. What could have been if they were allowed to do so sooner?
Tottenham Hotspur's season is suddenly looking up, having recorded a third successive victory.
A win over rivals Arsenal this week, even in the Capital One Cup, will cement the perception that everything is looking rosy again for Mauricio Pochettino's side.
Buying the South Korean forward from Bayer Leverkusen is already looking like an excellent piece of transfer business, acting as the catalyst for the club's recent upturn in form.
Yet once again it begs the question of what might have been, had the club got their act together quicker in the transfer market?
Chairman Daniel Levy has become notorious for waiting until late August and even deadline day to secure deals, rather than getting the club's important business done by the start of the season.
He may have failed to sign a centre-forward, but his additions of Son, and Clinton N'Jie could prove to be masterstrokes.
It is now late September and N'Jie is still to make his first start, which begs the question of why Spurs could have have pushed through sooner a transfer for a player they were linked with signing by The Sun back in June.
Would Son have made a different in a narrow defeat at Old Trafford? Would he have helped turn draws against Leicester, Stoke and Everton into wins?
Judging from his early season form, and the performances he has helped inspire from his teammates, Tottenham would be better off in the table than they currently stand.
Tottenham can't do anything about the transfer window ending when it does, but they can change their behaviour towards it and get their act together before the season starts in future.
The early impact of Son is testament to the fact they should have brought him in sooner; but only next year will fans learn if chairman Daniel Levy has finally learned his lesson.
