He has since gone on to lift three Scottish Premiership titles and should the Hoops beat Motherwell on Saturday, the centre-back will also make it back to back trebles. Getting him tied down to a new contract means Celtic fans can relax and watch him over the summer without worrying that a good performance is going to lead to bids and the player having his head turned. "I'm very proud and honoured to be able to commit my future to the club", Rogic told the Celtic website. He loves playing against Rangers - four of his nine goals came in Old Firm games, and he'll be back to haunt Rangers again now for the next five years.
"I'm working under a top class manager and to play my club football here is something that's very special to me so I couldn't be happier to have signed a new contract. Now that my future's sorted I can focus completely on playing football and giving everything I have for the club, as I have done for the past five years".
'The Scottish Cup final goal last season was a pretty special moment that I think will be hard to top. "I've committed my long-term future to the club I love, and that's all I can say about it".
"I have said it before that I am happy here".
The Belgian has made 37 appearances across all competitions this season and will find out next week if he has made Roberto Martinez's squad for the World Cup in Russian Federation.
