Former Rangers boss Pedro Caixinha believes that the Light Blues are still playing catch-up with Celtic almost three years after he left.
The Portuguese arrived at Ibrox in March 2017, signing a three-year deal as Mark Warburton’s replacement, but lasted just seven months, becoming the shortest-serving manager in the history of the club.
He was replaced with Graeme Murty on an interim basis, with Steven Gerrard taking charge in June 2018.
Rangers finished second last term and are currently 13 points behind Celtic as the Hoops look to bag a ninth consecutive league title.
