Celtic lack the fear factor they once possessed.
Celtic may be on course to retain their Scottish Premiership crown, but they have not exactly been convincing this season.
Hearts midfielder Arnaud Djoum even believes his side can win the league next season, currently sitting in third.
Speaking to the Scottish Sun ahead of the match between the two teams this weekend, he said: "The games we have played against Celtic this season have all been very close. I don’t sense that there is a big difference between us and them.
“The difference is not big between the teams but we have had some stupid red cards which have given us bad results.
"Celtic have not had a very big season and in the recent games, they have struggled a little so we have to believe that it is not impossible to get a good result."
Djoum's confidence in his own team is one thing, but it also displays that Celtic do not possess the fear factor they once did.
If Celtic are to become the force they were, and aspire to be again, they need to distance themselves from the pack, and show they are a dominant force.
That will mean hanging onto their best players, and investing well in the summer. Does it mean keeping manager Ronny Deila? It would be hard to part with him after two consecutive league title wins should they see this one through, but he will need to show the side is capable of more.
