"With the other players we won good things here and I am very happy to return from my injury".
The first blood score came in the 16th minute of the second leg match at Camp Nou.
Solskjaer admitted in the immediate aftermath of their 3-0 defeat in Barcelona, which sealed a 4-0 quarter-final win on aggregate for the Catalan giants, that he faces a major rebuilding job to re-establish United among the European elite.
Although De Gea has produced a number of brilliant saves this season - most recently during the West Ham victory - he has arguably dropped the most errors since his initial United move.
It's perhaps uncanny that De Gea has conceded two soft goals from the most lauded players in the sport, both on their weak foots, in the matter of nine months.
But after Marcus Rashford hit the crossbar in the opening minutes, Messi took over with his tournament-leading ninth and 10th goals of the season. The 31-year-old Argentine was left with a swollen nose and cheek following a collision with Chris Smalling during the first leg at Old Trafford.
2 - Ajax have won their last two Champions League away games, last winning more consecutively in the competition between November 1995 and March 1997 (seven). Donny van de Beek canceled out Ronaldo's opener before Matthijs de Ligt took the victor to let the Dutch visitors advance 3-2 overall.
Dispossessing Ashley Young on the flank, Messi cut inside and curled beyond De Gea, who four minutes later allowed the Barcelona captain's tame right-foot effort to slide under him.
That, however, was before Messi's quickfire double.
"It could have been different if we had started better and we got the first goal, but now we have to concentrate on next week".
He said: "The quality of their finishing was absolutely outstanding". He then turned Phil Jones inside out on the stroke of half-time to release Jordi Alba.
With Barca already well on the way to the last four by the 61st minute, Coutinho had nothing to lose when he unleased a majestic curling effort that raced into the top corner from 20 yards. It's a big week and we have to get ready for that week because (they are) three big games. In the 2018-19 season, he has 45 goals in all competitions.
