Andy Walker expects Rangers to duke it out with Celtic for the rest of the season, and believes a change in mentality has improved their title credentials.
Steven Gerrard 's side beat Hamilton 3-1 yesterday to move back level with their city rivals at the top of the Premiership, the Hoops having thrashed Livingston the previous day.
Only goal difference has Neil Lennon 's side at the top of the table, and Walker expects things to be close right up to the wire.
The former Celtic striker said on Sky Sports : (Rangers are) mentally stronger, mentally tougher, the players are absolutely focused on the job at hand.
"None more so than Alfredo Morelos. I know he was on the bench yesterday but this is a guy that scores regularly when he plays. He scores on the big occasion.
"You have a month coming up when Rangers and Celtic are going to be playing each other twice - once in the League Cup final and once in the league game just after Christmas.
"I think Rangers have shown that they are mentally tougher this time round. It's going to be neck and neck between these two sides, I think all the way to the last few weeks of the season."
