Chelsea’s Dutch international Arjen Robben has agreed personal terms over a move to Spanish champions Real Madrid, according to BBC Radio Five.

A transfer fee is yet to be agreed upon by the two clubs but according to reports from Spain the Chelsea winger’s deal is expected to fetch up to £15m.

Robben, who has two years left on his contract with Chelsea, has been a target for Real president Ramon Calderon since he was elected to his post two years ago.

“It is a negotiation which will take place in coming days or weeks,” Calderon told Spanish radio station Onda Cero.

“If the situation is favourable financially, I think that he is a player who could be brought in.”

Robben has been involved in protracted negotiations with Chelsea over a contract extension until 2012 but has yet to sign a new deal.

Chelsea manager Jose Mourinho is in no hurry to sell, saying: “The club wants to keep these players. I trust the board and our chief executive Peter Kenyon in the negotiations he is doing.

“I know the players want to stay and I would be happy if they signed.”

With the Blues having last week signed France international winger Florent Malouda from Lyon Chelsea may opt to accept Real’s offer for Robben. Indeed the club have already been linked with 20-year-old Dutch Under-21 star Drenthe, who would be available for £7m.
