The Old Firm are set to be reunited in the Scottish Premiership next season.
Former Celtic hero Kenny Dalglish has dismissed the suggestion that Celtic have wasted their chance to increase the gap between themselves and their bitter rivals Rangers ahead of their return to the top flight, the Daily Record reports.
The two Old Firm foes meet in the Scottish Cup semi-final this weekend in a game that arguably takes on extra significance as the Gers' Scottish Championship title win means that the game will become a league fixture from next season, so the Hampden Park clash may provide an indication of how the two sides will compare ahead of next year.
With the Light Blues spending the last four years in the wilderness of Scottish football, the Hoops have had the perfect opportunity to ensure that they remain unchallenged at the summit, even after Mark Warburton's men return to the top tier.
While they are well on course to win five league titles in a row - as they boast an eight-point lead over Aberdeen - questions have been asked about the progress that Ronny Deila has made at Parkhead seeing as the best the Bhoys can do this term is win the double.
But Dalglish has hit back at the suggestion that they should be doing more to widen the gap between themselves and their rivals.
He told the Record: "What more can Celtic do other than win the title?
"Celtic can only look after themselves and they won it last year and will win it this year.
"They can't get any better than first. They can't get any further away.
"Rangers have improved and I think it's better for Scottish football that these teams are closer."
While winning a league and cup double would normally be a tremendous achievement - an achievement that Celtic would have accomplished for a third time since Rangers' fall if they manage it this year - the fact that their usual sparring partners have not been at the top table has arguably meant that winning two trophies per season is a minimum requirement.
And with the club not making much of an impression in either the Champions League or Europa League since the Norwegian arrived, dominating the domestic game should be the target.
However, as Dalglish hinted at, Rangers' time in the lower leagues has probably hurt Celtic as much as it has benefited them.
The fact that the top division only consists of one heavyweight surely makes the league much less appealing to players that are considering whether to move to Celtic, or whether to stay at Celtic, which therefore leaves the Hoops with a difficult task if they hope to build on their success further.
