However, Moyes felt his team did give a good account of themselves for most of the contest.
He stated post-game: I think Mo (Kudus) had a great chance early on and I think (the front players) all did a really good job, both defensively and trying to break when we could.
We weren't good enough on the ball trying to build, to get us into better positions than we were, but I have to say their press was incredibly intense, incredibly fast, and the way they get the ball so quickly through the ball boys was something to see. It was something for us to learn."
He added: I thought they yellow cards for Lucas Paquet and Emerson were harsh.
I think if our bench all ran and surrounded (the officials) they way they did, the whole bench came off and you're not allowed to do thatI thought it was a really poor action from their bench."
On the away support, he finished: The support tonight was really good. They got behind us brilliantly well.
They probably appreciated that it was an incredibly tough game and we hung in. We've seen Leverkusen score a lot of late goals and I was really aware of that and was trying to find ways of tightening us up and shore it up.
But we lost two goals from corner kicks tonight, which for us is really disappointing."
