Manchester United goalscorers Memphis Depay and Marouane Fellaini were delighted after the 3-1 win at home against Club Brugge on Tuesday night.
The Dutchman scored his first two goals for the club and was key to United's comeback in the first half.
And the Belgian's last-minute goal means that the Red Devils take a two-goal lead for next week's second leg of the tie.
"It is really important we win the game," Depay told BT Sport.
"We created a lot of chances, I feel disappointed I could not finish the last two chances. We have to travel to Brugge and finish the job.
"I ended last season with a lot of goals, come to a big club and you have to do a good job again. It is a nice feeling to score two goals at Old Trafford.
"I am little disappointed because I will think about that last chance."
Last-minute goal-scoring hero Marouane Fellaini said: "It's a fantastic win today and we have to be careful in Brugge but we have the quality to win there as well. We have to be ready."
