Liverpool boss Jurgen Klopp knows his team will be professional on Thursday night.
The Reds have already qualified as group winners for the Europa League round of 16.
However, they still have to finish out their group games, taking on Union SG in Belgium.
Asked about already being top and through, Klopp told reporters: Look, we were a couple of times in this situation that we had to play the last game of the group stages [already qualified] but unfortunately not often enough as usually we have to go for everything and win it, in the past, in the Champions League, super-important games to get through the group stages.
We are through and we were that in the past as well. It is really important you find a group who can really fight in a game, who can really go for it, because that is the job to do.
We are physically in the situation to do that and from a determination point of view as well; I think we found that and I hope we can choose that line-up because you never know what happens overnight. The line-up in my mind, the line-up we used today in training, would mean we have a good mix between a bit more experience and youth. We want to go for it."
