In an interview with Gianluca Di Marzio, Kevin Mac Allister indicated he is considering a move to a higher level. He also stated that his goal is to play in one of the five major leagues. Mac Allister mentioned that he believes the Premier League is the best league, although he feels his qualities are not best suited for English football. He also expressed his appreciation for all the major leagues in Italy, Spain, France, and Germany. Kevin Mac Allister said he first wants to win one last title with Union.

Argentine centre-back Kevin Mac Allister, 27, stated to AS that he wants to stay in Europe, but whether that will be with Union or another team, he does not know yet. He also said that he has no specific preference and tries to live only in the present, adding that the next transfer period is still far away. Mac Allister added that he still has one and a half years left on his contract with Union, so at this moment he is not really thinking about a transfer. He said that this does not make much sense at this moment and that he is also happy at Union, where he is happy and the people like him. The defender, who joined his current club in July 2023, has made 12 appearances in the Jupiler Pro League this season and is valued by Transfermarkt at €7.50m.
