Steaua Bucharest officials were left red-faced after a prank organised by supporters of their arch rivals Dinamo Bucharest appeared to sabotage their pre-match display before the Champions League qualifier against Manchester City.

With anticipation high ahead of the visit of Pep Guardiola’s side, Steaua owner Gigi Becali had commissioned a “tifo” at the Arena Nationala in Bucharest to mark 30 years since their victory in the 1986 European Cup final. However, when the huge mosaic was unveiled just before kick off, it was revealed to say “Doar Dinamo Bucuresti” (Only Dinamo Bucharest).

According to reports in Romania, the display had been organised by a group of Dinamo fans who posed as professionals offering to help prepare the display before the match.

The evening went from bad to worse for Steaua, who suffered the heaviest home defeat in their history after a hat-trick from Sergio Agüero set up a 5-0 win.
