The defender endured a shaky start to life with the Scottish Premiership leaders.
The former Manchester City man endured a shaky start to life at Parkhead, but has been much more impressive in recent weeks, and Deila insisted that was due to the defender being able to build some momentum by holding down a place in the team.
"You have to remember that Dedryck came here and came straight into the team but he had not played regular football in his career before that," he told the Evening Times.
"He has started to settle and be more comfortable on the ball and he has struck up a decent partnership with Erik Sviatchenko.
"He was always going to need a little bit of time to adjust to playing regularly, not just in a physical way but mentally as well."
The 25-year-old was recalled to the side after over a month out of the team, following the injury to Jozo Simunovic. And while his first two appearances back in the side would have done little to suggest that he would be able to rival the Croatian upon his return from the sidelines - as the Bhoys were knocked out of the League Cup by Ross County and then beaten by Aberdeen in the Premiership - his performances in the last three games have been much more promising.
Playing alongside January signing Sviatchenko, Boyata has helped Deila's men keep three clean sheets in a row as the club have followed their victory over East Kilbride in the Scottish Cup by beating Ross County and Inverness in the league.
It was during the league victory over Ross that the Belgian proved once again the threat he provides in attack also, as he scored the second goal to essentially kill the game off and prevent the Staggies causing another upset.
And if Boyata and Sviatchenko's partnership continues to develop, then it seems unlikely that any team will be able to spring a surprise and prevent Celtic going on to clinch the title.
