In 2007, there was a bid from Liverpool to sign Gabriel Heinze from United, but United refused to allow him to join their biggest rivals due to the ongoing feud. United claimed that it was agreed Heinze would only join a foreign club if he chose to leave.[22] Heinze went public with his request to join Liverpool which was seen as the ultimate betrayal by the Manchester United fans. The Manchester United fans who once chanted "Argentina" in honour of the player then turned their backs on him. Heinze was eventually sold to Real Madrid instead.
