Celtic manager Neil Lennon has admitted that his title-winning side had no "credible" opponents in this season's Scottish Premiership title race.
The Bhoys clinched a third successive league triumph in midweek against Partick Thistle with seven games still to play.
With Rangers currently in Scottish League One, Lennon has admitted that he will simply concentrate on improving his team as their Old Firm rivals climb back up the league pyramid.
He told BBC Sport: "People are saying it's not the same, the competition is less.
"The competition is there but it's a fact that Rangers aren't there, that we don't really have, what you would say, a credible opponent at the minute.
"But we can't do anything about that. We just have to keep improving, keep progressing the players and keep being successful. And Rangers will be back, there's no question about that."
The Ibrox club have won this year's Scottish League One title and currently sit at the top of the table, 31 points ahead of their nearest rivals Dunfermline Athletic.
