Mac Allister remains central to Arne Slot's side, making 21 starts this season, but his output has dipped considerably, failing to score a goal, and registering two assists in a season that has been characterised mainly by disappointment.
However, speaking earlier this month, the midfielder insisted that their form is changing for the better, telling the club's website: "We feel like we are in a good moment, in a much better moment than the beginning of the season. We are improving as a team – which is the most important thing – and now we're looking forward to this amazing game.
"The manager had a really good meeting where he said that we needed to improve in both boxes. That's what we wanted and I think we showed it in the last two games.
"But we were more aggressive, we pressed a little bit more. That's what we want and that's what we want to get and be consistent on that. I think it's going to be key.
"We have many players that are injured, so it's not that easy, but we are getting there. I think we are all happy with our last two performances.
"We played against two teams that were a little bit more aggressive and tried to build from the back, which is for us maybe better. We are in a good moment but we need to keep working and keep improving."
