Chelsea target Kevin de Bruyne has revealed his frustration at not being allowed to complete a move from Racing Genk.
The Belgian starlet has been heavily courted by Blues boss Andre Villas-Boas since his arrival at Stamford Bridge, with the former Porto manager hoping to make the player his sixth young signing of the summer.
However, Chelsea were told on deadline day that the player would not be allowed to make an England move, despite the club's reported willingness to loan De Bruyne back to his homeland for a season.
"I'm disappointed in the attitude of Genk. I do not want any controversy, but I'm disappointed. Chelsea was a very nice offer, the club wanted me to stay for one year in Genk," said the 20-year-old midfielder.
"I hope it still goes on, because this is a dream for me.
"I wanted to give everything for one year in Genk and with a good feeling to say goodbye to the club and the supporters."
Player agent Patrick de Koster confirmed the party still hope a deal can be done in the future, and De Bruyne would join compatriot Romelu Lukaku at the club if a deal could be agreed to bring the player to Chelsea.
"We are having discussions about a transfer and I have a meeting with Genk and we will have to see what can be resolved," he told skysports.com.
"I think the discussions will be very long because I think we will need some time to find the right solution.
"But I would say that it is an opportunity for Kevin to make enormous progress in his career and that is the most important thing at the moment. We hope they will let him go."
Chelsea did strengthen in the window elsewhere though, with Juan Mata, Oriol Romeu and Lukaku the highest-profile additions during the summer.
