The Belgium international defender joined the Scottish Premiership champions from Premier League giants Manchester City in June.
The 24-year-old arrived as a replacement for the now-departed Jason Denayer, and he has already shown that he can be a success at Celtic Park.
Deila is pleased with Boyata and how he has settled in at Celtic so far.
“We had two top defenders last year, and Dedryck is starting the same way Jason Denayer did - scoring goals,” the Norwegian told The Scottish Sun.
“He is also very strong defensively, so I am happy with the signing. Dedryck is going to be an important player for us.”
Boyata has huge potential and could be an important player for Celtic for a number of years.
However, the real test for the Belgian will be in the Champions League.
The Bhoys should win the Scottish Premiership title this season with ease, but they are not guaranteed a place in the group stage of Europe’s premier club competition.
The Hoops simply cannot afford to lose out on a place in the group stage of the Champions League yet again if they want to make themselves a force in Europe in the coming years.
