Ajax star Dusan Tadic is sorry about the way his old Southampton team was broken up.

Tadic will face Tottenham in the first-leg of the Champions League semifinal this week.

"The first two seasons at Southampton were a great experience. We finished seventh and sixth under Ronald Koeman, the best results in the club's history," says the 30-year-old Serbian of his four-year stay in England.

"We should have gone on to do even better but once you get weaker in the Premier League you have problems. So many players were sold, Van Dijk, Pelle, Mane, Wanyama, Fonte, and the replacements were not so good."
