The Gers have made the perfect start to their league campaign.
Warburton’s men currently boast a perfect league record, having won nine out of nine, and have done so with consummate ease.
The Gers have rarely been troubled and have notched 31 times while only conceding five goals. Their scintillating form has led to claims that an unbeaten campaign is there for the taking, but MacDonald – who scored 51 times for Rangers in 336 appearances between 1968 and 1980 - thinks it will be tough.
“Personally, I think we could, but you could get injuries that might cost us and then if we get that far in front the manager could play some of the kids to give them a chance,” he said, in an interview on the club’s official site.
If Rangers maintain their current form, there’s every chance the Championship title is wrapped up with a good few weeks to spare and the urge to rotate the squad will be strong for Warburton.
A weakened Gers side with nothing to play for up against teams fighting for their lives is a recipe for trouble and could scupper hopes of an unbeaten season at the final hurdle.
Whether or not Rangers manage the impressive feat, the season looks certain to be a success and MacDonald is delighted by what he has seen so far.
“It’s been absolutely brilliant. The movement of the players is absolutely superb and you can see they are playing for the jersey and want to win, and that’s all the supporters want to see.
“There is a real feel-good factor, and that’s there even without the players on the park, but when the team are playing, it’s incredible.”
