The baby-faced assassin is a legend around Old Trafford.
Signing in 1996 just after Manchester United lost out to Newcastle for the signature of Alan Shearer, nobody had heard about this 12-year-old looking striker from Norway.
But one thing is for certain, by the end of the 90s, he had scratched his name on the lips of every United fan worldwide.
Scoring over 126 goals in 366 appearances in a career with The Red Devils that lasted 11 years, he became known as United's super sub.
Most notably, coming off the pitch to score four goals against Nottingham Forest in the space of 11 minutes in 1999.
That's the sort of raw talent and skill he had.
And oh yeah, he also did this too...
The biggest goal in Manchester United history that saw them collect an historic treble. The one that took them to "The Promised Land" as Martin Tyler famously said.
Now, he's back as Manchester United confirmed that he would take charge of the club on an interim basis until the end of the season following the sacking of Jose Mourinho.
Solskjaer lives, eats and breathes Manchester United but he's also a fan of another football club that dates back to the mid-noughties.

Stick him full-forward, lord knows Mayo could do with his goal scoring ability.
