Glasgow Rangers boss Mark Warburton recently completed a deal to bring the midfielder to Ibrox.
Niko Kranjcar in action for Croatia against Celtic and Scotland midfielder Scott Brown
Niko Kranjcar has insisted that Rangers have the ability to win the Scottish Premiership next season, but must not allow themselves to think that Celtic are a better team than they are, the Evening Times reports.
The midfielder completed his move to the Gers on Thursday as Mark Warburton continued his preparations for the new campaign.
And with many wondering just how well the Light Blues will fare at the highest level after several seasons away, the 31-year-old has claimed that they must believe that they are the best in the division as they have no reason to fear their Old Firm foes following last season's Scottish Cup semi-final victory over the Bhoys.
"I saw the highlights and heard about the great win in the semi-final of the cup," he told the Evening Times.
"It gives you reason to believe that you can win it and I have no doubt about it. You play football to believe in yourself.
"I am not going to sit here and say 'they are better than us'. They're not.
"We are going to say 'we're the best team in this league'. That's the way it has to be. The only thing left then is to prove it on the field."
Rangers players celebrate after winning the penalty shootout against Celtic
With the Hoops going through a period of transition, while Warburton's men may still have some of the momentum from last season's win over their rivals, this is arguably an excellent opportunity for Rangers to close that gap even further, and perhaps mount a challenge for the title.
And while last season's squad proved that they were capable of beating Celtic - albeit, only after a penalty shootout - it is arguably adding players like Kranjcar, Joey Barton and Clint Hill, who bring that experience and belief, that will surely boost the side's hopes of getting back to the summit of the division immediately.
