Liverpool boss Jurgen Klopp says Union SG deserved their Europa League on Thursday.
A youthful Reds lost 2-1 having already been confirmed as group winners.
Klopp said: "I think we definitely all saw the same game, so for us it was a deserved win for Union. Even though I heard now the first goal might have been offside but nobody can tell properly. We will see that, but who cares? They are well set up, they are top of the table, they played a stronger side, I mixed up the team completely, so I think the changes we made, the amount of changes, were too much for rhythm. We needed to grow into the game.
"I am really happy that happened in the second half more and more and that we gave it a game, a proper game in the end. Before that, they gave us possession, won the balls on counter-attack and it was really tricky, to be honest.
"It was pretty intense on a really difficult pitch. It was not great and you saw how intense it was, a couple of players had cramps for Union. So, in the end we could have scored the equaliser and it would have been nice, we would have loved to have got the point here. For some it was a really important experience and for others good for rhythm.
"I saw good performances and, of course, as a team it is not a fair assessment if I say now they are top of the table in Belgium and we come here, bring kids altogether that's really difficult. But I thought we gave it a go and that's OK for me. Nobody got hurt, nobody is injured, so we recover, go home and go again."
On Jarell Quansah scoring his first goal for Liverpool, Klopp also said: "It was important. I think we all know against Crystal Palace that he played not a bad game against Palace but if you are then that involved in kind of the penalty, a strange one, but we are involved, that's not cool.
"And I am really happy that he could see the other side of the metal and score this goal today. That's what I liked the most from all of the boys that they really gave it a proper go. And that's most important that we don't think, 'OK, it's difficult, they are a really good team and do what they do every week.' We have to find a way to get used to each other. And especially Jarell, with either side Ibou and then Joe in the second half, that was really good.
"They had to defend big spaces in the counter-attacks and I thought they did that really. So, really happy for him."
