Winning a couple of trophies, managing to keep a cool relationship with the fans and leaving the club is of course one option open to Deila. If he wants to be at the home of the SPL champions for the long run however he will need more than a lukewarm relationship with the supporters.
They are the heart of the club and have a huge impact on the players. It is their support and chants throughout a game that can spur the players on and potentially even put the opposition off.
Deila needs them onside and in a big way if he wants to be a Celtic legend.
