“We know what we want, we know what we need and we’re going to do everything we can to get that right next year.
“But, before that, we have a lot of games and we are looking forward to that, as well.
“They showed today that they can get results.”
A fourth successive European loss looked on the cards after Fenerbahce took the lead, Lizar Markovic scoring after a howler from goalkeeper Craig Gordon.
“He didn’t touch it, maybe because he was afraid to meet the goalkeeper and it’s gone through his legs.
Fenerbahce’s Diego, who had earlier clashed with Stefan Johansen, was dismissed for kicking out at the midfielder and substitute Kris Commons soon headed Celtic level.
Deila added: “Things turned around on the red card and also we brought on fresh legs and creative players in James Forrest, Kris Commons and Tom Rogic.
“The back four defended well, on the ball we can be better and also in the midfield – play passes forward instead of playing sideways and backward.
“These are things we have to work on. Overall, it’s a good performance and a good result. To get something from Fenerbahce is tough.”
