Ole Gunnar Solskjaer has made a very impressive start to life as Manchester United manager.
He's won each of his first six games, with Sunday's victory over Tottenham proving that he can challenge with the Premier League's top clubs.
United's fine form under the Norwegian is a contrast to performances under Jose Mourinho, who was sacked in December after a 3-1 loss to Liverpool.
The likes of Paul Pogba and Marcus Rashford are now flourishing at Old Trafford and the team have scored an impressive 17 goals in the last six games.
Much of the success is down to the players on the pitch, who seem to be putting more effort in each game. But of course, Solskjaer should be credited for bringing about that change in attitude.
There's been a clear shift in tactics too, with United now playing fast, attacking football - which opposes the style that Mourinho often deployed during his time in the hotseat.
In fact, attitude and tactics were the first things that Solskjaer wanted to change when he was handed the job on an interim basis.
That's according to his former teammate Teddy Sheringham, who has since revealed what the baby-faced assassin told him on the day he arrived in Manchester.
"The first thing is to smile when you’re at Manchester United because when it’s over you do miss it," Solskjaer told Sheringham, per the Mirror.
"It’s about attacking, about pace, about power. I know we [nodding to Teddy] didn’t have the best of pace but we still attacked."
Clearly, Solskjaer was far from impressed with how United had been playing over the last couple of seasons. So much so, that he couldn't help but take a swipe at Mourinho's tactics as well.
TAKING AIM AT JOSE'S STYLE
"That’s what Manchester United are built around – attacking football and going forward. Not stupid square and back passes."
To be honest, most United fans would share Solksjaer's opinion. Nobody wants to watch their team play boring, defensive football, especially if it leads to losing.
But still, the new boss put down a marker by taking a swipe on day one, and it seems to have sparked the players into life.
