Manchester United's comeback against Paris Saint-Germain in the Champions League is going to be spoken about for a very long time it seems.It's no exaggeration that the Red Devils had a mountain to climb after losing the first leg 2-0, especially because the second leg was away from home.Ole Gunnar Solskjaer was also without a number of first-team players in Paris, like Paul Pogba, Jesse Lingard, Anthony Martial, Alexis Sanchez and Nemanja Matic.But incredibly, two goals from Romelu Lukaku and Marcus Rashford's controversial late penalty turned the tie around.The away goals rule worked in United's favour as they drew 3-3 and progressed into the quarter-finals.Huge credit must go to Solskjaer, who has done a phenomenal job since taking over. Beating PSG at the Parc des Princes is unquestionably his greatest achievement as manager to date.But this is a man who's accustomed to great comebacks.Back in 1999, Solskjaer scored a last-minute winner against Bayern Munich in the Champions League final to win the game for United, who were 1-0 down until the 91st minute.Teddy Sheringham equalised before Solskjaer - who had only been on the pitch 12 minutes - prodded home at a corner to make it 2-1.Wednesday's comeback against PSG doesn't quite compare to that night in Spain, but it will certainly live long in the memory for United fans.So much so that a hilarious video has been made of United losing the first leg 2-0, Solskjaer saying "mountains are there to be climbed" and then the comeback happening. Check it out.

We don't know where the video originates from, but whoever made it deserves a pat on the back. The part at 1:16 where Solskjaer has been edited into the film 'Everest' is just perfect.

It's gone down an absolute treat with United fans.
