Ibrox side Glasgow Rangers have made impressive progress since Steven Gerrard took charge.
Rangers have struggled to keep pace with Celtic in recent campaigns, and Ferguson admits that it has pained him to watch his former side on occasions.
But Rangers seem to have improved considerably since Steven Gerrard took charge.
And Ferguson is convinced that Rangers can push Celtic all the way this time around.
He said: “For the first time, the six best sides in the country have the potential to take points from each other on a much more frequent basis and whoever wins the title this season is unlikely to do so with 90 points.
“It pains me as a Rangers fan to say my old club have too often been a painful watch in the last couple of years, but they’re showing signs of being a proper football team again.
“Now it’s up to Steven and his players to find their mojo on the road and prove something good is really happening on Edmiston Drive.”
Rangers are currently in sixth place in the Scottish Premiership table, but the league is looking congested.
Rangers are only five points away from the top of the table, and just two points behind Celtic.
Gerrard’s side won against Hearts in their most recent match, to ensure that they kept the optimism up around Ibrox.
Rangers are next in action in two weekends’ time, when they take on Hamilton.
