The tired champions' status as Scotland's superior side appears to be in danger at the start of 2003 after a draw at Pittodrie left them three points adrift of leaders Rangers.

Celtic were hoping to end the first half of the season by returning to the top of the Scottish Premier League with victory against the Dons.

And it looked good when Henrik Larsson scored his 30th goal of the season to give them an undeserved half-time lead before going off with a head injury with Rangers struggling.

But Russell Anderson scored a second-half header to give new manager Steve Paterson his first point against the Old Firm since taking charge.

And with Aberdeen unfurling the centenary flag and the red flares being lit before kick-off it certainly seemed to fire up the home side from the first whistle.

They twice went close in the first two minutes when first Darren Mackie headed Kevin Rutkiewicz's cross wide from five yards and again from Jamie McAllister's centre.

The visitors might have been boosted with big guns Larsson and John Hartson recovering from illnesses to play, but they certainly looked off-colour, especially at the back for the most of the game.

In fact Aberdeen were appealing for a penalty after five minutes when Kevin McNaughton went down in a heap under the clumsy challenge of Joos Valgaeren from Mackie's cross, but referee Mike McCurry waved away the protests from the home side.

Celtic continued to live dangerously and they survived another big shout for a penalty when Mackie went down heavily under the challenge of Bobo Balde this time.

Moments later and the Glasgow giants breathed another sign of relief when Chris Clark's corner broke to Russell Anderson on the edge of the area and his effort was deflected just past the post by Stilian Petrov.

On 24 minutes Celtic had the ball in the back of the net from their first quality passing move of the game when Larsson finished off Petrov's pass, with Hartson also involved, but the linesman ruled it out for offside.

They did, however, move up a gear and a deflected shot from McNamara, in for flu victim Didier Agathe, off the foot of McAllister whistled past the upright.

But from their next attack the champions took the lead and it was no surprise that it was Larsson who came to their rescue with the opener on the half-hour.

Hartson did well to find Sutton and from his ball over the top the Swede flicked the ball over David Preece and got in ahead of Philip McGuire to head the ball into the net.

While his team-mates celebrated his 30th goal of the campaign he remained grounded after colliding with McGuire, but soon recovered to the joy of O'Neill and the travelling fans.

The home side would have been lifted, however, moments later when a visibly-shaken Larsson was forced to leave the field and was replaced by David Fernandez.

It did not look like being Aberdeen's day until the 51st minute when Anderson rose unmarked in the box to glance McAllister's corner into the corner of the net from five yards with Hedman on the ground after coming to try to claim the ball.

O'Neill tried to be upbeat after the draw, saying:"It's not the end of the world - far from it," said O'Neill. "We have still taken a point and it's still in our own hands. We still have to play Rangers twice and after the Kilmarnock game I feel we have gained a point and it's still within our own grasp. We know that matches are always going to be difficult against them. But we are definitely looking forward to the break now. The players have played a lot of games and they showed today how tired they were and how much they are looking forward to the break and we'll see if we can refresh ourselves."

But another concern for O'Neill was the sight of Larsson forced to leave the field with a head injury.

"Obviously he is a bit dazed," added O'Neill. "But hopefully he will recover from that quickly."
