Rogne can be Celtic star says Southampton's Hooiveld
The Dutch defender played alongside the 22-year old Norwegian centre-back during his time with the Bhoys so is well-versed to comment on what his old dressing room mate is capable of and Hooiveld feels it will all be positive.
"Thomas has a big future. He has a lot of talent and has the physical power to play at a high level," he told SunSport.
"He has a good head on him. Between the ears everything is OK. He's a big talent and I'd like to see him stay at Celtic."
