Joorabchian snaps over 'inconsistent' West Ham

West Ham have been accused of double standards over the handling of Carlos Tevez. In an angry statement released late last night on behalf of Tevez's owner Kia Joorabchian, West Ham were accused of failing to act upon 'repeated promises and assurances'.

Sportsmail understands there is explosive documentation held by Joorabchian that, until yesterday, was likely to remain out of the public domain.

Now, with his patience wearing thin, he says he will bring "the true circumstances" to the attention of FIFA and the FA.

In a statement released by his lawyer Graham Shear, Joorabchian said: "We as a company have patiently kept away from the issues including West Ham in order to give the club the opportunity to resolve the matter in a legal and agreeable way.

"West Ham have consistently provided private assurances while making contrary statements to the public at large.

"We can no longer allow these inconsistencies to continue unaddressed.

"During his time at West Ham Carlos Tevez performed at a high standard. There was a period at the end of last year when Carlos had the opportunity to leave the club and yet he decided to stay to successfully help West Ham survive in the Premier League.

"We wish to make clear that at all times it has been our intention to find an amicable solution and Carlos Tevez has, at no time, acted improperly in relation to his move to Manchester United as he was given permission via his representatives to talk to other clubs to reach an amicable agreement.

"Over the past six months West Ham have made repeated promises and assurances which they have not acted upon or performed. It is time for these inconsistencies to be brought to an end.

"We see no alternative but to bring the true circumstances to the attention of a higher authority to aid a rapid conclusion to this issue."

Joorabchian was alongside Tevez in Manchester yesterday and is determined the transfer of his prize asset will be concluded.
