Deila ready to get Celtic firing after admitting horror start so stressful
The Norwegian took over from Neil Lennon in June and was thrown into the crucial Champions League qualifying campaign the following month, which ended with fingers pointing at the former Stromsgodset boss when the Hoops failed to get through the play-off stage against Slovenian side Maribor.
The fact that Celtic had been given a reprieve after losing 6-1 on aggregate to Legia Warsaw in the third qualifier when the Polish side fielded an ineligible player in the second-leg at Murrayfield, only brought more criticism as the Parkhead club dropped into the group stages of the Europa League, which begin next week with a trip to Salzburg.
