The Australian says the Norwegian has been key to his resurgence this season.
There is no doubt that Rogic has improved this season. He has played 17 times for Celtic this term, scoring five times from midfield as he finally lives up to the promise with which he arrived in Glasgow.
The youngster arrived from Central Coast Mariners already a fully-fledged Australian international in 2013, but he has struggled with injury and form during his Glasgow stint.
This season has seen him overcome his fitness woes and put in some excellent performances for The Bhoys and he says Ronny Deila is a big part of that success.
Speaking to the Australian Daily Telegraph the playmaker stated:
“Having the confidence of my club manager is massive. He’s been a great influence, given me a lot of confidence to go out there and play and enjoy my football.
“When the manager came in I spent the first year at the club injured, didn’t play at all. Towards the back end of last season when I started getting to full fitness, we sat down and he assured me that I had a future at the club.
“He’s been fantastic for me, I enjoy playing for him. It gives me a lot of confidence, and makes me want to improve all of my game, using every session and every game as an opportunity to improve.”
The Norwegian boss has found himself under pressure in recent weeks. Whilst Celtic are now cruising in the domestic league their failures in Europe have once again angered the fans at Celtic Park.
Two defeats to Norwegian side Molde has left them on the verge of elimination from the Europa League, after previously failing to overcome Swedish champions Malmo in Champions League qualification.
But Deila clearly seems to have the backing of Rogic, a player who has come on leaps and bounds under the divisive Celtic boss.
The young Australian is clearly one man who would not like to see Deila leave the club.
