Indeed, speaking during a pre-match press conference ahead of Celtic's Scottish Premiership season opener against Ross County on Saturday afternoon, Deila revealed what he sees as the club's biggest advantage in Azerbaijan.
According to the Norwegian, Qarabag will be forced to attack during their home leg, meaning more space will be created for the Hoops to retaliate, unlike the close opening clash.
And that leaves Deila in confident mood ahead of the second leg, as he told reporters.

Confidence should not turn into complacency, however, as Celtic prepare to travel abroad to secure their place in the Champions League play-offs. Dedryck Boyata's goal sealed an impressive result for the Hoops on Wednesday night as the Scottish champions left Parkhead with both a win and a clean sheet.
But a one-goal lead is a slender one going into the reverse fixture. Scoring first in Azerbaijan would mean Qarabag would have to score three to go through due to the away goals rule - but Celtic must keep a cool head in order to do so.
