Valencia claim Manchester United want to sign their Argentine World Cup star Ariel Ortega. The Spanish club say Old Trafford have opened negotiations for the attacking midfielder, but yesterday United chairman Martin Edwards denied that he is trying to land the £9 million-rated striker who is currently on Valencia's transfer list. Ortega's Argentine team-mate Gabriel Batistuta has said he wants to leave Fiorentina and would also be keen on a move to Old Trafford.
