Yes, the Hoops kicked off the Glasgow derby campaign with a 3-0 victory in September and followed that up with a nail-biting penalty shootout win in the Premier Sports Cup final.
Celtic were not at the races that day with the match finishing 3-3 after 120 minutes. But lady luck was on their side at Hampden Park from 12 yards out.
But the Bhoys then lost the following two derbies to Rangers, the most humbling a 3-0 Ibrox loss at the start of January.
The next one was more painful given Celtic fought back from 2-0 down, only to fall to a 3-2 scoreline as a result of Hamza Igamane’s late winner.
Celtic captain Callum McGregor, however, wants to put things right this Sunday and play out the final Glasgow derby of the season with an away triumph.
Boyd wary of McGregor’s defiant Rangers vs Celtic statement
And that feeling inside the Celtic camp, despite already having the title wrapped up, definitely caught the attention of former Rangers striker and current Sky Sports pundit Kris Boyd.
Boyd, writing for The Scottish Sun, admits Rangers need to be wary of Celtic’s hunger to bounce back from the previous two derby defeats as a result of McGregor’s six-word statement.
Boyd clearly sounds concerned. He wrote: “I tell you what, though. They better be ready for Celtic coming for them because, from what Callum McGregor has been saying this week, they are desperate to win.
“‘We want to put things right’, was how he put it.”
“He could easily have talked about how Celtic are champions, and that this derby doesn’t really matter in the context of the season.
“But his message was that Celts aren’t happy with how they have done against Rangers this season, and how they have to change that at Ibrox in tomorrow’s derby.”
