The former Rangers captain won five league titles at Ibrox and is aware of what is needed to win back-to-back leagues with the Glasgow giants.
Ferguson conceded that winning any league title is hard, but feels the hardest part is ahead for Rangers as he believes it is even more difficult to retain it.
He stressed that as Rangers achieve more success going forward the pressure to win more and retain league the title is only going to increase tenfold.
The Rangers legend feels Steven Gerrard and the players will know that they will be under the cosh next season and will also have to show progress in the cup competitions.
Ferguson said on the Go Radio Football Show: “It is really hard to win a trophy, especially if it’s a league.
“The hardest thing is to retain it, then build on it and then keep winning and winning and the pressure keeps mounting.
“They will be under pressure next season, the manager will know that the players will know that so the next aim is to go and build on winning the league.
“Go and retain the league and go on bring the League Cup and the Scottish Cup back.”
Ferguson is realistic about Rangers’ prospects in the Champions League and believes making the group stage will be the limit of their ambitions.
“I don’t think they will get really far [in the Champions League], I am being realistic here.
“The aim is to get into the group stage.”
Champions League football is sure to boost Gerrard’s budget and the Rangers boss looks set to add to his squad in the summer window.
