Deila has been in charge of Celtic since the start of the 2014-15 season, while Warburton was appointed the Rangers manager in the summer.
Celtic and Rangers are the two biggest clubs in Scotland, and pressure on the two managers is huge.
There is a lot of scrutiny, and both Deila and Warburton come under pressure when their teams lose or perform poorly.
Warburton is probably still getting used to life as a Rangers manager, and Celtic boss Deila has a piece of advice for the Englishman.
When asked about what Warburton will be experiencing, the Norwegian told The Daily Record: “Because I’ve been through that it will be easier for me to go to another club in the future with the same intensity around it.
“Advice? Learn quick. That’s the most important thing. You have to use a lot of time for reflection. Know yourself, what you stand for, who you want to be, what you want to achieve. Then you have to go for it and believe in yourself.
“You have to adapt to the culture here and the environment around you too. When you get the time to reflect, you understand how much you’ve learned. But in the middle of it you just take one day at a time.”
Celtic are at the top of the Scottish Premiership table at the moment with 39 points from 16 matches, four points clear of second-place Aberdeen with a game in hand.
Meanwhile, Rangers currently find themselves at the top of the Scottish Championship table with 40 points from 15 matches, three points clear of second-place Hibernian.
