Colby Donovan shines, appalling teammate gets 2/10 - Celtic player ratings vs Rangers
Dan Neil's first-half strike set Rangers on their way, before Kevin Kelsy's volley doubled the lead, with Neil then adding a stunning third in the 75th minute.
Martin O'Neill's side struggled to ever truly impose themselves on the game, and failed to create opportunities for their attacking talents to shine.
The result means that Celtic have already missed the opportunity to lift one trophy just weeks into the new campaign.
It was a hugely frustrating afternoon for the Bhoys at Ibrox, who simply could not live with their rivals' intensity and quality.
With that in mind, Football Insider rates the performances of every single Celtic player, following an abject performance from O'Neill's men.
Sam Johnstone appalling on Old Firm derby
Celtic goalkeeper Sam Johnstone was one of several players on the pitch who played in their first-ever Old Firm derby on Sunday.
However, it was a torrid afternoon for the Bhoys' new shot-stopper, who looked shaky from the very first kick and failed to instil any confidence in his teammates.
The 33-year-old's distribution caused issues for his team all afternoon, and a misplaced pass almost gifted Kelsy the opener inside the first 10 minutes.
Johnstone also looked extremely uncertain when it came to commanding his area and dealing with the set pieces that the hosts aimed into the box.
On the whole, it was a hugely concerning display from the veteran gloveman, who was worthy of little more than a 2/10 rating.
Colby Donovan the only bright spark
Colby Donovan had a difficult afternoon up against the lively Djeidi Gassama, but he largely marshalled the winger well through the 90 minutes.
He was left walking a tightrope for over an hour after he was booked just before the half-hour mark, but he didn't let that detract from his display.
It was far from a perfect performance from the young right-back, but he was arguably the only Celtic player to show any desire and pride in the shirt.
Donovan is always up for the battle of an Old Firm clash, and that was no different on Sunday, as he fought hard for every ball until the very end.
He was arguably the strongest performer for the Bhoys on the day, but even so, didn't justify any more than a 6/10 rating.
