Ex-Liverpool defender takes aim Arsenal keeper for poor mistakes.
Petr Cech is no longer a great goalkeeper, according to Liverpool legend Jamie Carragher.
The former Liverpool defender blamed Cech for his part in Manchester City 's opening goal against Arsenal - a Kevin De Bruyne left-footed strike in the first half at the Etihad.
"Petr Cech should save that," he said on Sky Sports. "I think he is one of the great goalkeepers in the Premier League, but now he's just a good goalkeeper."
