The Celtic boss has been discussing his side's pre-season preparations.
The Bhoys traveled far and wide for friendly matches earlier this campaign and ultimately paid the price when they were knocked out of the Champions League qualifying rounds - twice.
But Deila says Celtic will be doing things differently next season. Indeed, the Hoops boss is already planning for next term and wants to play fewer games and travel less.
The changes will allow for more preparation time, Deila explains, and a more positive set of pre-season results.
"We are going to play fewer games, travel less and prepare for those games. I want to do it differently than last year," the Norwegian told reporters.
"I think we did way too much travelling and played way too many games. It is not positive to play games with half a team and lose 5-1 and 6-1. It is not positive for the confidence. We don’t like to lose.
"We want to be as well prepared as possible when we play and that is going to be the main issue now in pre-season."
Celtic travel to St Mirren in the Scottish Premiership later today, sitting five points clear of second-placed Aberdeen with a game in hand over the Dons heading into the clash.
A domestic treble is still very much on for the Bhoys, then, as they are also in the semi-finals of the Scottish Cup. But their Champions League adventure was short lived this term.
A thrilling tie with Inter Milan was their reward for getting through the Europa League group stages - but Deila's side would no doubt rather be facing similar opposition in Europe's premier competition.
