Real Madrid are reportedly unhappy with UEFA's decree that they must wear their green kit for Tuesday's Champions League last-16 clash with Manchester United.

It has been reported that the Spanish outfit wanted to wear their usual white strip for the second leg at Old Trafford, but United refused to change their white shorts to black.

According to various reports, players at Madrid have been left disappointed by the decision, with many seeing the green outfit as an unlucky omen.

However, Madrid have knocked out United the last two times playing in their away kit.
