The Gunners slumped to a frustrating 2-1 defeat at arch rivals Tottenham on Sunday in a match which they dominated for long spells, but were severely punished by two lapses in defensive focus just before half-time.
They have no FA Cup quarter-final tie to look forward to this weekend after they crashed out at home to npower Championship side Blackburn, with scheduled Barclays Premier League opponents Everton still in the competition.
So Arsene Wenger's battle-weary squad will at least have some extra time to prepare for what looks an impossible mission in Germany when they will attempt to overturn a 3-1 last-16 first-leg deficit.
The players were back at the club's Hertfordshire training complex as the group aim to refocus for the run-in, which Wenger accepts will provide a "massive challenge" if Arsenal are to somehow force their way back into the Champions League qualification places.
Szczesny, though, insists no-one can afford to dwell in any self-pity as they aim to tackle those seemingly lost causes head on.
"Every time we lose a derby there is going to be disappointment, but we have to pick ourselves up. We have 10 days until the next game so we have to make sure we are prepared for that," the Poland goalkeeper told the club's official website, www.arsenal.com.
"We have a lot of time to prepare for that game and if we manage to get a good result and hopefully qualify for the next round, that would be a massive boost to have a good run in the Champions League."
