Celtic are at the top of the league table at the moment with 73 points from 68 matches, five points ahead of second-placed Aberdeen.
The Bhoys have the strongest squad in Scotland, but their results and performances this season have been disappointing.
Although Ronny Deila’s side are still favourites to clinch the Scottish Premiership this campaign, there is a good chance that the race for the title could go into the final weeks.
Adam, who started his professional club football career at Celtic’s bitter rivals Rangers, believes that the Hoops will win the league title in the Scottish top flight.
The Stoke midfielder has also shared his hopes about Rangers, who will take on the Hoops in the semi-finals of the Scottish Cup at Hampden Park this month.
Rangers have already won the Scottish Championship title this season and have gained automatic promotion to the Scottish Premiership.
Mark Warburton’s side will face Peterhead in the final of the Scottish Challenge Cup on Sunday afternoon before taking on Old Firm rivals Celtic.
Adam hopes that Rangers are able to win both games and maintain their chances of winning the treble this campaign.
"Celtic are dwindling at the top, they've taken their foot off the gas and Aberdeen have pushed them all the way, but they will still win the league,” Adam told Sky Sports.
"I'd like to see Rangers push them and hopefully get the win, and to try and win the treble in one season would be incredible."
