Rangers keeper Ivor Pandur is convinced their Old Firm double-header success proves they can win the title.
The new Ibrox No.1 has been a major success since his summer move from Hull City, after predecessor Jack Butland headed in the opposite direction.
Pandur is in his homeland preparing for Croatia's Nations League fixtures against Czech Republic, England and home and away fixtures against World Cup holders Spain, after he was named in Slaven Bilic's squad.
He kept two clean sheets as Rangers beat Celtic 3-0 in the Premier Sports Cup at Ibrox before following it up with a 1-0 win at Parkhead in the league.
And the 26-year-old reckons that could put down a marker after he admitted he's stunned at how busy he has been since his move north.
Pandur said: "We play Celtic four or five times, it could be six, depending on the other cup.
"So a lot will depend on those matches, but I also think every game matters.
"They are great, they really have a great team and a recognisable style of play.
"They have had the spine of their team for years and add really good players to that.
"It won't be easy, but I believe that we will be the ones who will win trophies in the end.
"Of course, we have to believe that, but that's why we are all here. We all knew from the moment we signed for Rangers that we were aiming for every trophy.
"Everyone told me when I signed, I would have 20 easy games a season and that I wouldn't have anything to do for a lot of them.
"And since I came here, it's been the opposite!
"Every game reminds me so much of the English Championship. Everyone we have faced has played well and nothing has been easy.

"The league is really tough and there's more quality than I thought, so it just makes everything even more interesting.
"And the Old Firm is something unreal. The amount of noise, the amount of cheering and how much it means to people.
"The fans want to pay you for everything, they want to give you everything. They really live for that club, they love it so much and everything depends on that result for them.
"When you see the importance of all that, it brings out the best in the players. I think everyone wants to play in front of 50,000 or 60,000 fans in that atmosphere.
"I believe Rangers and Celtic think very similarly. They both always want to win every game. Every season they aim to win everything, regardless of what they're playing in - the Champions League, the Europa Conference League or whatever.
"They have that mentality, that they want to win every match. They have high expectations. So I came here too because, of course, like everyone else, I want to win trophies. That's our primary goal."
And Pandur, in an interview in his homeland, has no regrets about swapping a chance to play in the English Premier League with Hull City for Rangers.
But he admits he would love to play there one day in the future.
He said: "It was very easy to sign for Rangers - we agreed everything quickly and everything turned out great. In two or three days I had my medical, signed and joined the team.
"You don't really know how big Rangers are until you get there.
"Then you see the people around and inside the club and it becomes clear to you.
"Rangers were interested in me for a few years- even when I was in the Netherlands at Fortuna Sittard, the directors who were there at the time were contacting me and asking questions.
"But they brought Jack Butland in and I went to England and that was basically it for those two and a half years, until Jack Butland went to Hull and I went to Rangers!
"The deciding factor was that I wanted to fight for trophies and be in a dominant team.
"I had European competitions in my head, unfortunately, which didn't happen, at least this season.
"I wanted to compete with the best. Even though the league is not the English Premier League - and I absolutely understand that - the Premier League wouldn't mean much to me if I didn't play as much as I wanted to play.
"So Rangers presented me with the opportunity to start again from scratch and I was very happy that it happened that way.
"I believe that I will get to the Premier League in a roundabout way. When? Only God knows. It's up to me to believe, to work, to do everything right and if I'm good enough, I'll be there for sure."
