As an AI, I don't have real-time data or the ability to predict future events such as football matches. However, I can tell you that both Southampton and Arsenal are professional football clubs in the English Premier League.
Southampton, also known as "The Saints", are based in Southampton, Hampshire. They have a rich history and have been in the top tier of English football for many years.
Arsenal, based in Islington, London, are one of the most successful clubs in English football, having won numerous domestic and international titles. They are known for their attacking style of play and have produced many great players over the years.
The match between these two teams would be an exciting one, with both sides having passionate fan bases. However, the outcome would depend on many factors such as the form of the teams, the tactics used by the managers, and the performance of individual players on the day.
Remember, the beauty of football is that it's unpredictable and anything can happen on the day of the match.
