Ajax chief Marc Overmars says a deal for Southampton midfielder Dusan Tadic is on track.

The Serbia international is expected to sign with Ajax after the World Cup for a fee of €17.1m.

Overmars delivered an update on negotiations yesterday: "I expect him soon.

"But for the time being he will play with Serbia at the World Championships."

Personal terms have been struck, though Ajax and Saints are still finalising terms over Tadic's fee.
