The Celtic boss was speaking to reporters ahead of the Bhoys' Qarabag tie.
Indeed, the Bhoys got past Stjarnan in their last European clash but now face Azerbaijani side Qarabag on Wedneseday night.
Charlie Mulgrew, however, is a doubt. Indeed, Deila says the 29-year-old is still 'struggling' and doesn't rate his chances of making the Qarabag tie too highly.

The Norwegian, meanwhile, is 'excited' ahead of the tie as it provides the Hoops with a big test.
Home advantage is something Deila has emphasised repeatedly in the build-up to the European tie and he once again stressed that factor during his press conference, telling reporters:
RD: “Feeling very well. I’m really looking forward to the game. It’s a big test for us." #UCL (MH)— Celtic Football Club (@celticfc) July 28, 2015
RD: "We are at home at Celtic Park, so I'm excited." #UCL (MH)— Celtic Football Club (@celticfc) July 28, 2015
If Celtic can bypass Qarabag, they really will be mightily close to the Champions League group stages and will have made a much better fist of things this year compared to last term. Nothing should be taken for granted, however, and a strong first-leg performance at Parkhead will be a necessity.
