Speaking to club media, Mac Allister said: "I think the team is still in a period of transition, which is quite normal. Jurgen was here for a good few years. For example, there are some players who had only ever played under Jurgen and had never had another coach. So, it is a significant change within the club, but I think Arne came here with very good ideas and I think that the whole group and the fans can see what he is wanting to do and the ideas he is wanting to express in the team."
The 25-year-old added: "We're all very happy and feel really positive about what is ahead. As I say, we've a lot of games coming up and there's a lot of competition, and that's what we like; this squad is full of great players, and we can take on board the tactical ideas that Arne wants to implement. But as I mentioned, we are in a transitional period and looking to put in place the ideas and concepts that Arne wants us to."
