The young Belgian again impressed in the quarterfinal triumph.
"Bentley is a different type of player to Lennon, so you have to approach it differently. In the last 10 or 15 minutes Lennon came to my side and I had to think again because I had to change my approach. But as a professional footballer you have to learn to adapt to the game," De Laet told MUTV.
"We knew that if we won this game we'd get at least two more matches in the semis so it's always good to progress," he said. "It looks good if you get to the final, and then you have the chance to win it. The first-team lads always come and tell us we're doing well, and we just need to do what we do in training. It gives you confidence."
