For all those doubting Manchester United, Sunday afternoon was quite the shock.
Rival supporters had been quick to trample on the hype surrounding Ole Gunnar Solskjaer by reminding everybody that the Red Devils had only played weaker Premier League opposition.
Wins over Cardiff City, Huddersfield Town, Bournemouth, Reading and Newcastle United weren't enough to convince fans there'd been a true post-Jose Mourinho renaissance.
Victory at Tottenham, however, certainly did with the Red Devils delivering a mature performance that resulted in a 1-0 scoreline virtue of Marcus Rashford's winning goal.
They needed some heroics from David de Gea - who made no less than 11 saves - throughout the game, but it was a convincing showing nonetheless.
100% record under Solskjaer
It will also give United fans plenty of confidence going into some of the tougher February fixtures under Solskjaer, who remains rather inexperienced despite his knowledge of the club.
But there has been plenty of reason to suggest that Solskjaer has had the right mindset from the very start, even before he was appointed the interim manager.
That's because the 45-year-old decided to pay a visit to Old Trafford back in October, watching the 1-0 defeat to Juventus and taking his place in the director's box alongside Ryan Giggs.
Solskjaer's comment to Giggs
And Giggs has revealed exactly what Solskjaer said about the performance while speaking to Premier League productions. It summed up his coaching style from the very start.
Per the Manchester Evening News, when asked about the changes Solskjaer had made, Giggs answered: "It's little tweaks. It's like you see with golfers.
"Just a little tweak to the game that someone else on the outside might have seen. Ole's been to a few games before he took over.
"I was at a game next to him, and he was pointing out to me, 'Look at the full-backs, they're not high enough'.
"Things that we were used to, things that you associate with Man United teams."
Not attacking enough and not Man Utd enough, in summary.
What has Solskjaer changed?
It was clear from that comment back in October that, if Solskjaer was pulling the strings, he would have gone for a more attacking approach. Fast forward to January and he's done just that.
"'OK you score two, we'll score three' and I think he's brought, he's instilled that back into them that we need to score goals, we need to attack and if we're all higher up the pitch then it just poses the opposition that question," Giggs elaborated.
"All of a sudden teams are going from, 'Right it's Man United, we've got a chance today' to actually, 'Oh yeah, we'll be defending, we'll be deeper'.
"With the front players that United have got, not only the starting players but the ones coming off the bench, you've seen Sanchez, you've seen Lukaku now having an impact.
"It rivals any team within the Premier League the firepower that United have got."
