The Celtic manager has been discussing using Tottenham as an example of how to achieve success.
Indeed, the Norwegian is keen to learn from others and has name-checked the likes of Tottenham and Bayern Munich.
The Bhoys boss is quoted as saying by the Express: "There are a lot of clubs I want to look at. Tottenham are doing very well and I always watch the Champions League and follow what is happening there.
"You have Pep Guardiola at Bayern and it seems he has taken them to another level.
"Talking with coaches and people who have a lot of experience is important because it gives you confirmation and new knowledge."
Reasons to be cheerful...
Tottenham fans will certainly be glad to hear the Celtic boss has mentioned them alongside Bayern Munich. Although the claim Guardiola has taken a treble-winning side to 'another level' without having won the Champions League is always debatable.
But there are certainly reasons to be optimistic if Deila is looking to learn from such clubs. Tottenham's relative success so far this season under Mauricio Pochettino - and we'll see whether that success has a shelf life - hasn't come from rocket science.
Spurs have blended together a group of young, hard-working players: a rather basic but hard-to-dispute strategy. Should Celtic look to do the same, their side will have bags of energy without any 'big-name' superstars. One drawback, potentially, is a lack of wisdom and experience older players might bring.
