Image source, Getty ImagesSolskjaer's playing CV is unquestionable - a cabinet full of trophies and goals in the biggest games for Manchester United, including that goal in the German's net back in 1999.
His managerial record is less impressive. He has won league titles in Norway with Molde but his previous spell in English football ended with relegation with Cardiff.
After appointing the Norwegian, Ed Woodward, United's executive vice-chairman, said: "Ole is a club legend with huge experience, both on the pitch and in coaching roles.
"His history at Manchester United means he lives and breathes the culture here and everyone at the club is delighted to have him and [assistant manager] Mike Phelan back.
"We are confident they will unite the players and the fans as we head into the second half of the season."
Can he succeed this season where the Special One has failed?

So it is clear Solskjaer's time as a player at United has played a big part in him getting the job as interim manager.
But what if a similar situation arose at your club?
If your team needed a new manager and the only option was to appoint a former player then which club legend would you choose and why?

The former striker has been plucked from his job in his home country of Norway to come and manage one of the biggest clubs in the world for the rest of the season.
He says he would love to have the role for longer than that but that will come down to results, starting with today's match at Cardiff.
Cardiff v Man Utd (17:30 GMT)
Image source, Getty ImagesThere's no question what the biggest story of the week has been. Jose Mourinho's sacking was in some way expected but it still caused a shock when it arrived on Tuesday.
The Portuguese departed with United sixth in the table, 19 points behind leaders Liverpool.
United have won just one of their last six Premier League games. Will Mourinho's departure signal the start of an improvement at Old Trafford?
It's also a big day at the bottom too.
14th-placed Newcastle play bottom club Fulham.
Second bottom Huddersfield host fourth bottom Southampton.
Burnley and Cardiff play Arsenal and Manchester United respectively, looking for a crucial surprise win.
That means Manchester City must beat Crystal Palace at 15:00 GMT to avoid losing ground in the title race.
Arsenal can close the gap on the top four in the early game too.
Image source, ReutersLiverpool beat Wolves on Friday night to extend their lead at the top of the Premier League to four points.
Mohamed Salah scored the first and set up the second, which was turned in by Virgil van Dijk in a 2-0 win.
The Reds remain unbeaten and have 48 points from 18 matches.
Manager Jurgen Klopp described their showing as "perfect football".
We have eight Premier League games coming up today.
First up is Arsenal v Burnley from the Emirates Stadium as the Gunners try to close the gap on the top four and Burnley try to move out of the bottom three.
Man City are also in action, looking to move back to within a point of Liverpool, while later Ole Gunnar Solskjaer leads Man United for the first time at 17:30 GMT.
There's no Christmas cheer for Jose Mourinho.
His time at Manchester United is over. For now at least one of the club's favourite sons is at the helm.
Today Ole Gunner Solskjaer manages his former club for the first time on a bumper Saturday of Premier League football.
It's the day the festive period really begins...
Last Christmas, I gave you my heart
But the very next day you gave it away
This year, to save me from tears
I'll give it to someone special...
