Southampton midfielder Dusan Tadic hasn't ruled out joining Ajax this summer.

The Serbia international is a top target for Ajax this summer.

Tadic told Voetbal International: "As long as nothing has been signed, I cannot say anything about it. First the signatures, then talk. And there are no signatures yet.

"At the same time I am working on a World Cup and we have suffered a defeat that has hit us hard."

Tadic is tied to Saints until 2020 and is the subject of a €17m offer from Ajax. On the table from the Dutch is a four-year contract.
