Kylian Mbappe, striker of Paris Saint-Germain, believes he would have killed the tie if he had defeated David de Gea in his duel.
In the 60th minute Mbappe brought the PSG 2-0 at Old Trafford in the game and was able to expand the lead three minutes later, but his Dink was excellently parried by the outstretched arm of the United goalkeeper.
"We are upset because we could have scored a third goal," said Mbappe, who also had a great start in the first half. "I think it would be over with a third and I will prepare to score another goal in the second leg!"
PSG lost a 4-0 first-leg advantage against Barcelona two years ago when they were beaten 1-6 in the second leg of Camp Nou. The Ligue 1 champion still has to reach a Champions League semi-final and hobbled in the last 16 stages against Real Madrid last year.
