Guadalajara have given up all hope of signing Nery Castillo on loan after their latest attempt to acquire the Shakhtar Donetsk striker was delayed due to the Ukraine club not completing the relevant paperwork.
Guadalajara vice-president Nestor de la Torre said on Tuesday that the club had reached an agreement with the player's agent, Juan Carlos Padilla, to sign Castillo, who is currently on loan at Manchester City, for the remainder of the season.
However, the Mexican club were today blaming Padilla for the breakdown of the deal.
They claim Padilla had guaranteed that Shakhtar had completed the relevant paperwork and that it would be sent to the Mexican Football Federation (FMF) for their approval by the start of this week.
But after that paperwork failed to arrive at the FMF, the club themselves made contact with Shakhtar who informed them they were not willing to release the 24-year-old striker.
A club statement read: ''Due to the informality and lack of reliability demonstrated by the representative of the player, in the future there will no longer be any negotiations to get the services of Mr Nery Castillo.''
Castillo had been training at Guadalajara this week because he has been unable to secure regular first-team football at City this season under manager Mark Hughes, who has told the player he does not feature in his plans at Eastlands.
