Solskjaer was unfortunate to lose Martial and Lingard to muscular injuries before the start of the second half, and their withdrawals not only critically diminished United's ability to pin PSG back and defend from the front, but also served to highlight the squad's lack of depth.
The interim Norwegian coach watched United overwhelmed by the French champions in the second half at Old Trafford with Presnel Kimpembe and Kylian Mbappe netting to leave PSG in the driving seat before the second leg in Paris on March 6.
The English giants will also have to cope without Paul Pogba in three weeks' time as he was sent off for two yellow cards a minute from time to round off a awful night for the hosts. There were concerns about how PSG would fare without the likes of Neymar and Edinson Cavani, but Mbappe made those worries disappear in the first leg against United.
As Di Maria sent in a cross, Mbappe darted between center backs Eric Bailly and Victor Lindelof and clipped the ball under goalkeeper David de Gea for his 23rd goal of the season.
"The second goal was quality by them". "I just want to keep enjoying my football, being useful to the club and my team-mates, whether on the field or if needed off it". Now it is more hard for us but, as I told you before, we have good examples.
But having come off the bench to score the victor in the 93rd minute of the 1999 final against Bayern Munich, Solskjaer is the man who epitomised more than most the "never say die" attitude of many Sir Alex Ferguson Manchester United teams. "We knew they wanted to score and we did it". The game was Solskjaer's first outing in Europe since taking charge. We have to learn from this.
Aside from victories in north London against Arsenal and Tottenham, facing PSG was United's biggest test since beating Italian champion Juventus at Turin in November in the group stage.
'This won't be a season-defining experience for us. First goal when they got that one - it was a poor goal to give away from a set-piece - then they got the momentum. A repeat of that 3-0 win in Paris next month would take United through to the quarterfinals.
