London - Petr Cech insists shell-shocked Arsenal will make amends for their Champions League meltdown by winning this weekend's north London derby.
Arsene Wenger's side suffered a potentially fatal blow to their chances of making the last 16 in Europe's elite club competition after crashing to a dismal 5-1 loss against Bayern Munich on Wednesday.
The Gunners' joint-heaviest European defeat leaves them in severe danger of missing the knockout stages for the first time in 16 years.
But veteran goalkeeper Cech knows they have a chance to erase those painful memories when they return to Premier League action against arch rivals Tottenham at the Emirates Stadium on Sunday.
"Every game comes thick and fast and you have to make sure you recover and move onto the next one," said Cech, whose second placed team have won their last five league matches and are behind leaders Manchester City on goal difference.
"The defeat to Bayern is tough to take but in a way you have to accept the team you played was superior to us in everything they have done.
"In terms of the league, you have to make sure you are ready for the next game."
