United Unhappy Over Liverpool/Heinze Affair

Manchester United have launched an investigation into Liverpool's conduct over Gabriel Heinze's protracted move away from Old Trafford, manager Alex Ferguson said on Friday.

Heinze was wanted by Liverpool until a Premier League arbitration panel upheld United's claim that the Argentina international was not permitted to move to one of their major domestic rivals.

Defender Heinze instead sealed a transfer to Real Madrid this week but United are not prepared to let the matter rest.

Liverpool manager Rafael Benitez had expressed his anger that Heinze had not been permitted to move to Anfield, claiming that the tribunal had wrongly sided with United when making their decision.

Ferguson was disappointed about the stuff he has come out with.
