Yaya Toure's agent is unhappy with the price-tag Barcelona have placed on the Ivory Coast international midfielder.
Toure has been linked with a host of clubs including Manchester City, Chelsea and Arsenal after slipping out of the first-team reckoning at the Camp Nou.
However, Toure's agent, Dimitri Seluk, is becoming increasingly frustrated by the lack of progress in a potential transfer, saying: "The problem is that Barca are asking for too much money because Yaya's demands are totally within reach of the clubs that want to sign him.
"The problem is what Barca are asking for. I would prefer him to play for Chelsea because they are a very strong team who have been in the elite for many years and who always aspire to be the best, but they won't pay so much money.
"As things stand, it is possible there is no definitive agreement before the World Cup. The ball is in Barcelona's court."
