Ole Gunnar Solskjaer couldn't have hoped for a better start to life as Manchester United manager.
The Norwegian boss made it eight wins from eight games played as United beat Arsenal 3-1 in their FA Cup fourth round clash.
Romelu Lukaku has been criticised in recent times but he was the architect for United's opening two goals.
He produced a lovely reverse pass for Alexis Sanchez to open the scoring and, minutes later, he then set up Jesse Lingard to make it two.
Pierre-Emerick Aubameyang pulled one back just before half-time but they could not find an equaliser.
And Anthony Martial emerged from the bench to put the result beyond all doubt, firing home with eight minutes left of normal time.
It was a pleasing result for everyone connected with Man United.
Getting one over Arsenal is always a good feeling for United fans and a tweet from an Arsenal fan after the game is making fans of the Manchester club feel even better.
In what can be only be described as an outburst, Arsenal fan @PatrickTimmons1 tweeted: "We sold them RvP & gave him a guard of honour.
"Their C team ended our title challenge in 2016. They milly rocked in our own stadium.
"They had their worst start to a PL in 28 years & caught up to us within a month.
"Then out-of-form Alexis scored on his return. I need a lie down."
It seems United really have embarrassed Arsenal in recent years.
In fairness to the fan, he has just summarised what most Arsenal supporters think after years of torment at the hands of their rivals.
The fan's rant was quickly picked up by United fans who replied with delight.
Ole Gunnar Solskjaer commented how his side looked like a 'proper team' in the win.
"It's fantastic to go through in the cup. It's one of the hardest games you can get," he said, per BBC Sport.
"Today we looked more like a proper team. We looked more structured. We'd worked hard at defending and counter-attacking. Counter-attacking is classic Manchester United - Wayne Rooney, Cristiano Ronaldo, Ji Sung-park - we've scored so many at Arsenal over the years.
"Today was a big step forward. It was a massive improvement from the Tottenham game. It's easy to get excited and talk about the future but we need to just keep working and think about the next game.
"We had to dig deep. The attitude and work-rate was important. Towards the end it was comfortable but not during the 90 minutes."
