Luis Suarez's Liverpool to Arsenal transfer case could end up in a Premier League arbitration hearing The most notable case presided over by the Premier League also involved Liverpool, who in 2007 tried to sign Gabriel Heinze from Manchester United. Heinze took United to arbitration, claiming they had given him written permission to pursue a transfer to another club. However, the panel decided that the letter in question did not constitute a binding agreement for United but only an "agreement to agree" and thus did not constitute an obligation to sell the player. The panel also agreed it should be interpreted in context of verbal discussion and the club's policy of not transferring players to Liverpool. The Premier League arbitrated in Charlie Adam's 2010 dispute with Blackpool, ruling he could not terminate his contract over the non- payment of a bonus despite finding in his favour over the unpaid sum. Mario Balotelli was set to take Manchester City to an arbitration panel in December over a club fine before dropping the case at the last minute, while Swansea narrowly avoided being taken to arbitration by Neil Taylor, who was interested in a move to Newcastle before signing a new contract. There is also the prospect of Liverpool making a formal complaint to the Premier League about Arsenal's bid for Suárez. Contract clauses are usually confidential and Liverpool themselves were fined £20,000 in 2002 for making an illegal approach for Christian Ziege after meeting his precise Middlesbrough release clause.
