The 20-year old Australian midfielder made his Hoops debut last weekend against Inverness before watching from the stands as his teammates lost 3-0 to Juventus in the Champions League at Parkhead during the week.
Rogic, who played the final 20 minutes in the 6-2 win over Dundee United on the weekend, says the atmosphere he experienced at Celtic Park for the European match was like nothing he had seen before and is thrilled to now be contributing to the fortunes of the Glasgow giants.
"I have never experienced being part of a sporting event like that, with the fans and the atmosphere they created," Rogic told the club 's official website.
"Obviously it wasn't the result the team wanted but I definitely enjoyed being there.
"It's special. When I walked out and sat in my seat, the crowd just got up and started singing 'You´ll Never Walk Alone' with the scarves everywhere.
"I'm really enjoying my time here and have only had good experiences so far, so hopefully that continues, and I can get to play more football."
