The Bhoys boss has been discussing his future once more.
Deila is facing pressure after four winless games in the Europa League group stages, the latest of which saw the Bhoys lose 2-1 to Molde at Parkhead on Thursday night.
Last season, the Norwegian failed to make the Champions League group stages. And the failure was repeated this time around, except for the fact Celtic now look as though they won't even make it to the knockout stages of the Europa League.
But Deila has used history to explain why the Hoops should stand by him. Indeed, the 40-year-old feels many previous managers in his position failed in Europe initially - but got it right with time.
RD: When you see the history of this club they have had managers before that have struggled in Europe in the beginning.— Celtic Football Club (@celticfc) November 6, 2015
RD: But they make it right and they stand by their manager.— Celtic Football Club (@celticfc) November 6, 2015
RD: I expect that as well. I really want to be here, I love the club and fans and if there’s someone who’s ambitious it’s me.— Celtic Football Club (@celticfc) November 6, 2015
Deila also explained how well he had slept after Celtic's 2-1 loss to Molde. The answer is not very...
RD: If there’s somebody sorry then I can assure you I didn’t sleep much last night but I see talent and progress.— Celtic Football Club (@celticfc) November 6, 2015
Celtic host Ajax in their next Europa League clash, before finishing their group stage with a trip to Fenerbahce. Whatever happens domestically, a dark cloud will hang over Deila and his side unless they can pull off a minor miracle in their next two European fixtures.
