Real Madrid lose $440 million sponsorship battle with Abu Dhabi fund

MADRID (Reuters) - Spanish soccer's Real Madrid have lost a $440 million court battle with Abu Dhabi sovereign investor Mubadala over the proposed sponsorship of its stadium in Madrid, sources with knowledge of the case told Reuters.

Real Madrid had claimed 400 million euros ($440 million) from Mubadala because it said the Abu Dhabi sovereign investor failed to honour a sponsorship deal under which it would acquire rights to name the Santiago Bernabeu stadium for 20 years.
