Feyenoord are demanding Aston Villa come clean over their interest in defender Ron Vlaar.

Vlaar has given Aston Villa 24 hours to sort out his transfer from Feyenoord.

Angry Feyenoord boss Ronald Koeman said: "That's a transfer fee every English club can pay for a top class central defender.

"We have to play a Champions League qualifying round in a week's time. I can't sit waiting until Aston Villa have finally decided what they want to do.

"It is about time they give the player clarity.''
