"We are full of self-confidence, positive energy and we have definitely shown that we are better than Celtic.
"How good we are this season is also confirmed by the fact that we secured the title two months ago.
"But it is not over yet, because we have two games left in the league, in which we want to celebrate and finish the season undefeated in the league and with more than 100 points won.
"All this is the result of incredible dedication and exceptional quality work with our manager. It means a lot to us that the majority of the team has been together with Gerrard for three years. We know each other by heart, we already have a lot of great results and performances.
"Of course, we have had some disappointments, but we learned lessons and got to where we are today.
"I've personally had a great season and I am delighted because I have played 56 games for Rangers and Croatia this season, which is a record for me, which practically no problems.
"At Rangers, we use the wings a lot and that is good for me. The manager trusts both me and James Tavernier, the other full back."
And Barisic, in an interview with homeland publication, Sportske Novosti, admits he can't wait to face Scotland at Hampden at Euro 2020 this summer.
He said: "Now I am seriously concentrating on the Euros. It's time to prepare and think about the games.
"It's obvious our aims are to get out of the group, which will not be easy at all, but we know our strengths, and I believe in a very successful Euros for us.
"I am also really happy we are playing in Scotland - a country which has grown close to my heart."
