Celtic’s disappointing run of form has seen manager Ronny Deila’s job come under pressure of late.

There have been intense calls for the Scottish club to dismiss the manager in the hope of improved results. Deila has done a decent job after coming as the replacement for Neil Lennon in July 2014. However, his record looks good only when domestic titles are concerned. Celtic have been majorly disappointing in European competitions and this has often been the yardstick on which they have been measured as a club in recent times. This is due to the decline of Scottish football in general.
