Georgios Samaras opened the scoring for Celtic in the 14th minute
By Martin Conaghan
Celtic recorded their fourth straight win in a five-goal thriller against Motherwell at Fir Park.
A Georgios Samaras strike gave Celtic the lead before Lukas Jutkiewicz back-heeled in a 26th-minute equaliser.
Mark Reynolds converted a Tom Hateley free-kick on the stroke of half-time then Aiden McGeady levelled shortly after the break with a curling shot.
Barry Robson missed a penalty before sub Marc-Antoine Fortune's shot claimed the points with 11 minutes remaining.
The win puts Celtic two points clear at the top following an action-packed afternoon in Lanarkshire.
Tony Mowbray kept with the side that beat Aberdeen last week, with Samaras partnering Scott McDonald in attack, while Gary Caldwell partnered Glenn Loovens at the back.
Motherwell boss Jim Gannon made three changes, with Steve Jennings, Steven Meechan and Robert McHugh all coming in - while Giles Coke, John Sutton and Ross Forbes started on the bench.
Celtic edged out Motherwell in a thrilling match at Fir Park
With the fog descending over Fir Park, Jutkiewicz cleared the air with an early effort from 20 yards out, but Loovens blocked.
Motherwell keeper John Ruddy deflected a Samaras shot off the bar after the Greece international struck from close range.
Celtic's opener arrived in the 14th minute from the boot of Samaras after the former Man City striker picked up a long ball from Landry N'Guemo and twisted around the Motherwell defence to fire in a superb shot from 12 yards out into the top corner of the net.
Moments later, McGeady forced Ruddy to parry a chipped shot and fired in with another low strike two minutes later.
With 25 minutes played, Jutkiewicz broke free inside the Celtic penalty area but lost out to a well-timed Loovens challenge.
The Englishman landed Motherwell's equaliser 60 seconds later after McHugh delivered a fine cross from the right for Jutkiewicz to back-heel past a hapless Artur Boruc.
Celtic remained composed as a Caldwell header inched past Ruddy's right-hand post just after the half-hour mark.
As half-time approached, Jamie Murphy gave the Celtic defence a scare with a blazing run into the penalty area, but Loovens and Caldwell cleared the danger.
Motherwell took the lead on the stroke of half-time when Hateley delivered a searching free-kick that was nodded down by Loovens for Reynolds to shoot past Boruc from six yards.
Celtic restored parity six minutes after the restart when Samaras sent a square ball to McGeady on the right-hand side of the Motherwell penalty area and the Republic of Ireland international curled in a superb shot past Ruddy.
Claims for a Celtic penalty were waved away by referee Charlie Richmond after Steven Jennings appeared to accidentally handle the ball.
Scott McDonald struck the Motherwell bar from a Danny Fox cross as the hour mark approached and a goalmouth scramble ended with a Samaras strike being deflected over.
Steven Saunders conceded a penalty in the 64th minute following a collision with Samaras, but Robson's spot-kick was parried by Ruddy to maintain the deadlock.
A McGeady volley inched wide with 20 minutes left as Celtic pushed for a lead and Jutkiewicz blasted a left-footed shot wide of Boruc's goal at the other end.
Samaras linked up with Robson in the 76th minute and looked certain to score but fired straight at Ruddy.
Substitute Fortune was on the pitch less than 60 seconds before he latched on to a Hinkel long ball and thundered in an unstoppable shot to put Celtic back in the driving seat.
With six minutes left, Ross Forbes delivered a low shot that drifted past Boruc's left-hand post then failed to test the Polish keeper with a long-range free-kick.
Fortune struck the Motherwell post with an angled shot in the final minute, but the points were already on the board for the Glasgow visitors.
Motherwell manager Jim Gannon: "I'm really proud to be involved with such a good game. It was a great advert for the SPL.
"You can see the quality of Celtic's play, and you can see why they've had four wins in a row now, but my players certainly gave a good account of themselves and showed what they are about.
"It was good to see our young players give a good account of themselves against such a quality team.
"We were confident we would score and create chances, which we did.
"But - great credit to Celtic - they've got the quality, they've got the intensity from their experienced players to be able to really put you under a lot of pressure and it told in the end."
Celtic manager Tony Mowbray: "It was a great football match with a lot of good play.
"From our perspective, we looked in total control of the football game in the first half, but we came in 2-1 down after shooting ourselves in the foot.
"But we got the job done, which is all-important at this stage - to keep picking up the points - and I think we warranted them.
"I think Marc Fortune has had a rough few months with his injury, but there's a lot of expectation on his shoulders.
"He can score goals at any level and I'm delighted for him."
