Chelsea winger Arjen Robben is 'happy' to be attracting interest from Real Madrid, according to reports in Spain. Dutch international Robben, 23, has been linked with a big-money move away from Stamford Bridge all summer. Currently battling to overcome a knee problem to be fit for the start of the new Premier League season, Robben was not included in the squad for the FA Community Shield against Manchester United at Wembley. Since then fellow Chelsea player Michael Ballack has come out and declared his commitment to the west-London club following reports he too could be heading to the Bernabeu. No official word on any offer for Robben has been forthcoming from either of the teams involved. However, in comments reported today by Spanish daily AS, Robben made no secret of his desire to take on a fresh challenge, having joined Chelsea for £12million in 2004. 'Of course Madrid's interest makes me happy,' he said. 'But for now I can not say much more because Chelsea will not let me tell you more until there is an agreement between the two clubs. 'It's better that they talk about it and solve this.' Robben, whose father and agent Hans has indicated negotiations were at a delicate stage, added: 'I do not know when a deal will be reached. It's in the hands of the two clubs. My father is in charge of it all. 'I know some people are waiting for me. 'I would like to send a message to the Madrid fans, but I can't until my future is sorted. 'If it gets sorted, I'll be glad to send the people a message.'
