Chelsea's Dutch international winger Arjen Robben says contract talks with the FA Cup winners over a new five-year deal are not progressing smoothly.
Chelsea paid PSV Eindhoven over £12m for Robben
Robben, 23, has been linked with a move to Real Madrid and his future has been further clouded by Chelsea's signing of Lyon winger Florent Malouda.
"We will see what the future brings," Robben told BBC Five Live.
"I haven't signed a new contract and it hasn't gone really well," added the Chelsea winger.
Robben, 23, joined Chelsea from PSV Eindhoven for £12m in 2004, and was recently the subject of an approach from Bayern Munich.
"I think for any individual player it's good when there's interest from any big club in the world," said Robben.
"It just shows that you're a good player and I always see that as a compliment.
"It was the same when I was at PSV in Holland before I went to Chelsea. There were a lot of clubs interested in me but it's just good for the confidence."
The winger is one of manager Jose Mourinho's key players but his progress at Chelsea has been hampered by a succession of injuries.
Last season, a thigh strain and knee injury kept him on the sidelines for several weeks of the campaign.
However Mourinho says he is keen to keep Robben, despite Malouda's arrival.
In July 2006, Chelsea threatened to have Real investigated by football's world governing body, Fifa, for what they considered to be an illegal approach for Robben.
Real president Ramon Calderon has previously claimed that his sporting director Predrag Mijatovic had spoken to Chelsea owner Roman Abramovich with a view to discussing a deal for the Dutch player.
At the time, Chelsea chief executive Peter Kenyon responded by stating: "We note that Mr Calderon confirms Real Madrid spoke to Arjen.
"As a result Chelsea will be writing to Fifa to ask them to investigate an illegal approach by Real Madrid.
''There have been no meetings or conversations between the Real Madrid sporting director Predrag Mijatovic with any Chelsea officials, anyone mandated to act on Chelsea's behalf or owner Roman Abramovich about Arjen's future."
