Fedor Chalov opened the scoring late in the first half and then Kirill Nababkin scored early in the second period.
Both goals came from rebounds after saves from the former Chelsea goalkeeper.
The first was a good stop from the Arsenal goalkeeper, but his save went straight into the path of Chalov who tucked in from a close range.
The errors from Cech aren’t the first the 35-year-old has made this season and the latest had many Arsenal fans calling on him to retire.
The disappointed fans reacted through their Twitter handles:
@alleyne_kammies, “Petr Cech really is done as a top goal keeper the man needs to retire.”
