FC Twente have told Tottenham to come clean if they're serious about Nacer Chadli.

Twente want £7.75million for the 23-year-old - who has just one year left on his current contract and wants a move to White Hart Lane.

The club's chairman Jens Munsterman said: "We hear a lot about Tottenham but the club will have to put up a concrete offer first.

"So far, only Swansea and Shakhtar have made concrete offers and are still options, even though Nacer decided not to go to them.

"We hope for some clarity this week."
