NAC Breda have given striker Maceo Rigters permission to open transfer talks with Celtic.

The 23-year-old has two years left to run on his Breda contract but has become hot property since finishing as top scorer for winners Holland at the European under-21 Championship.

Breda director of football Earnie Stewart told reporters: "We are in the process of negotiating a new improved contract with him.

"But, if he wants to speak to Celtic, then there is nothing we can do about it because it's all been done by the book.

"Celtic have faxed us a note of interest and are the only club so far to do that."

Rigters hit four goals for Holland's youngsters in their European finals campaign but has not been a regular scorer at club level, netting just three times in 32 league appearances for the Dutch club last season.

Newcastle are also said to be monitoring the striker's situation.
