The businessman who claims to control Carlos Tevez is threatening to appear as a witness for Sheffield United if they win the right to a High Court challenge over the Premier League's handling of the affair.
The appeal is scheduled for tomorrow and such is Kia Joorabchian's frustration with the Premier League after it blocked Tevez's £35m move to Manchester United that he is considering contacting the Sheffield United chairman, Kevin McCabe, to hand over key documentation. Joorabchian believes he has evidence that would prove damaging to the League and West Ham, Tevez's present club. He considered appearing as witness for the Blades at last month's arbitration hearing but decided against it.
Now Joorabchian feels he may have little choice but to become involved if Tevez is to win the right to move clubs. The Premier League claim the undertakings given to them by West Ham - that the striker was solely their player and that a side agreement did not exist - mean that they cannot cancel Tevez's registration and allow him to leave without keeping most of the fee.
Joorabchian argues that West Ham teared up the agreement he had with them - that Tevez was only on loan for a season - and that they had no right to him if they decided against using a £40m buy-out clause.
Sheffield United accept that there is no time for them to be reinstated to the top-flight but are demanding up to £50m compensation because West Ham were fined rather than deducting points over the controversial signings of Tevez and Javier Mascherano.
Privately, West Ham realise that they are in a mess over the affair, while the Premier League is threatening them with the possibility of a second inquiry. That would raise the prospect of a points deduction this season.
