Neil Lennon has been open about his struggles with alcoholism in the past. As such, it is reasonable to consider whether this could be a potential problem if he were to become the manager of Aberdeen Football Club. However, it is worth noting that Lennon has been sober for several years and has publicly spoken about how important it is to him to maintain his sobriety.
Ultimately, whether or not his alcoholism would be a potential problem would likely depend on how well he is able to maintain his sobriety while managing the team. If he is able to continue to prioritize his health and well-being, and is able to effectively manage his addiction, then it is possible that it could be a non-issue. However, if his alcoholism were to impact his ability to manage the team or his behavior towards players, staff, or fans, then it could become a problem that would need to be addressed.
