The Bhoys goalkeeper has been discussing his side's excellent defensive record.
The likes of Efe Ambrose have sometimes looked worryingly shaky in defence for the Bhoys but Deila's men have largely impressed in that department, conceding just 16 times in 32 Scottish Premiership games.
And Gordon says his manager deserves plenty of credit for the way in which he has changed things around at the back.
The Scottish shot stopper told the Celtic View: “We’ve not conceded many goals in any competition really. We’ve been working on that from the very start of the season as the manager wanted us to defend in a slightly different way.
“It was something that we had to work on and now that we understand the gist of what he was trying to get us to do, it’s certainly working well."
Naturally, Celtic's defence has also been aided by personnel as well as tactics, with Gordon admitting centre-backs Virgil van Dijk and Jason Denayer are two of the best players he has ever played alongside.
The Bhoys goalkeeper hasn't done too badly himself, of course, producing several magnificent displays for Deila's side so far this term.
Will Celtic's defence be tested as they close in on the Scottish Premiership title? And how will they fare in this weekend's Scottish Cup semi-final? Gordon, Van Dijk, Denayer and co will no doubt relish the challenge.
