Tony Watt scored a double on his first Celtic start as Neil Lennon's injury-hit side swept to a 4-2 victory at Inverness.
The 18-year-old produced a brilliant piece of skill, a good turn of pace and a composed finish in the 24th minute to add to Victor Wanyama's early headed opener.
Charlie Mulgrew fired Celtic three ahead just after the break and Watt was on hand to make it 4-0 in the 64th minute.
However, Celtic switched off the final 10 minutes and Ross Draper scored two consolations.
Dundee United's hopes of maintaining their 100% record and top spot were undone by suicidal second-half defending as they lost 3-1 at Kilmarnock.
A comedy of errors inside the first five minutes allowed Rory McKenzie and Borja Perez to claim their first goals for Kilmarnock before Jude Winchester grabbed the home side's third inside 10 minutes to give Kenny Shiels' side their first win of the season.
And although Jon Daly pulled one back for the Tannadice side it did little to placate manager Peter Houston, who was raging on the touchline throughout the second half.
Hibernian made it back-to-back wins in the SPL with a 2-0 success against St Johnstone at Easter Road.
The home side were second-best throughout the first half but took a 1-0 advantage into the break thanks to a 45th-minute goal by Paul Hanlon. Eoin Doyle added the second six minutes after the restart.
The defeat leaves St Johnstone joint bottom of the division with only one point taken from their opening four games, while Hibs move up into second.
A Richard Brittain penalty was enough to give Ross County their first SPL win of the season over Dundee.
The Staggies, now unbeaten in 38 league games, netted the winner with less than 20 minutes remaining after Mark Corcoran had been impeded by Neil McGregor.
The defeat leaves Dundee at the foot of the table with only one point from their opening four matches.
