Steaua Bucharest's stadium display before Tuesday's Champions League match against Manchester City was sabotaged by rival supporters in what has called one of the biggest pranks in football history.
Undercover Dinamo Bucharest fans planned the prank perfectly. They placed coloured vests on the chairs in a section of the stands at the 55,634-seat National Arena in the Romanian capital and put them on just before kick-off.
Instead of displaying a message celebrating Steaua's 1986 win, theirs said: 'Doar Dinamo Bucharest' (Only Dinamo Bucharest) in the red-and-white colours of Dinamo.

Steaua's owner Gigi Becali, 58, had wanted to put in place a special fan choreography right before kick-off in order to honour his team's European Cup final win in 1986 against Barcelona.
