Petr Cech is OUT of Arsenal's FA Cup final with Chelsea after manager Arsene Wenger chose to drop him.
The Guardian says Cech was expected to start behind the injury-ravaged Gunners defence but he has been axed in favour of Ospina in a shock move from the under-fire Frenchman.
Cech had suffered a slight knock but thought he had recovered in time to play – the goalkeeper is reported to be 'devastated' by the decision.
Wenger – who has a section of the Arsenal crowd calling for his head – is already without Laurent Koscielny and Gabriel Paulista and is trying to save his season.
Ospina has not started a game since the Premier League draw with Man City at the start of April.
But he will have Arsenal's season in his hands at the weekend when only a win will do after they dropped out of the Champions League place.
