United advanced to the last 16 of the Europa League with goals from Dalot and Kobbie Mainoo against FCSB, winning 2-0.
Dalot opened the scoring by converting Mainoo's low cross, and Mainoo sealed the victory.
Dalot told MUTV: "I think the first half was just us trying to understand where we could hurt them. Obviously in the second half with Amad and Garna (Garnacho) we had a bit more of a threat inside the final third and were a bit more direct.
"But overall, I think we controlled the whole game. Even after the first goal, we conceded one or two chances that could have changed the game, but I think that was more through a lack of focus than from the opposition.
"Overall, I think we are really happy with the performance, the result and another clean sheet, which is also important for us. We have gone into the next phase directly, and that was what we wanted. It was really good from us."
