The Saints returned to winning ways in the Premier League with a 6-1 hammering of Villa at St. Mary’s Stadium.
The star of the show for Southampton was Senegal international winger Sadio Mane, who scored a hat-trick in the opening 16 minutes.
Shane Long found the target twice in the first half, and Graziano Pelle volleyed home the sixth goal for the home side nine minutes from full time.
Following the win, Southampton boss Koeman made the following post on Twitter:
2nd biggest home win this season. What a great way to celebrate our last home game today. Team and fans deserved it! pic.twitter.com/tCiSl59msM— Ronald Koeman (@RonaldKoeman) May 16, 2015
Southampton are currently sixth in the Premier League table with 60 points from 37 matches.
The Saints still have a good chance of making it to the Europa League next season. Their final game of the season is against former Premier League champions Manchester City away from home at the Etihad Stadium.
