Thanks for your company tonight when St Johnstone not only improved their own chances of finishing in the top six of the Scottish Premiership but kept the title race alive for Aberdeen as they try to hang on to Celtic. Join us on Friday when Queen of the South host Falkirk in the quarter-finals of the Scottish Cup.
- Danny Swanson's goal gives Saints victory
- Leaders Celtic remain six points clear
- St Johnstone move above Dundee into sixth
- Celtic miss out on ninth straight league win
"Celtic have been so good recently and weren't quite there tonight, but you can't put that down to the European game last week. You've got to give so much credit to St Johnstone for a wonderful performance."
"It was a big setback. It is disappointing, but it's happened now and we have to learn from this and it's four days before we can make it good again.
"We didn't create anything in the wide areas and it was so crowded in the centre it caused problems.
"Nothing is finished and we make it difficult for ourselves. This is not good enough.
"There were some tired players out there, but we should be better as a unit."
"We can't say tonight and say St Johnstone had a smash and grab. They came here, played Celtic and deserved their win."
That has brought to an end Celtic's 11-game unbeaten run in domestic football.
Celtic were looking for a ninth straight league win. Instead, they suffered their first home Premiership defeat in nine games since Hamilton left with a 1-0 win on 5 October.
"The goal was worthy of winning any game. It was a tremendous strike.
"Danny phoned this morning and said he didn't think he was going to make it and we're glad he did.
"We asked them to be brave in possession and I thought we were.
"We controlled and passed the ball really well and that gave us the platform to go on and win the game.
"It shows a lot of character and belief in one another."
Celtic have used up their game in hand over second-top Aberdeen. That just about keeps the title race alive despite the leaders' 4-0 win over the Dons on Sunday as there are still only six points separating the top two sides.
St Johnstone just about deserved that surprise victory because of their second-half performance and a superb winner from Danny Swanson. It moves the Perth side back above Dundee into sixth spot and they are now equal on points with fifth-top Hamilton Academical.
Celtic are trying desperately to equalise, but St Johnstone are holding on bravely as we have two minutes of stoppage time to play.
Celtic midfielder Stuart Armstrong is fortunate not to be shown a second yellow card as he shoves Lee Croft to the ground.
"If they win tonight, they go back into the top six. On their performance tonight, St Johnstone are definitely a top-six side."
Virgil van Dijk rises above the St Johnstone defenders to meet a corner kick, but the defender heads wide.
Steven MacLean tees up Chris Miller 20 yards from the Celtic goal, but the midfielder lashes his shot wastefully over the crossbar.
It is Stuart Armstrong's turn to get a shot on target, but St Johnstone goalkeeper Alan Mannus again holds.
Celtic midfielder Nir Bitton gets a shot on target, but goalkeeper Alan Mannus shows strong hands to save.
Celtic's players are becoming frustrated and Stuart Armstrong is booked for a foul on Lee Croft before Michael O'Halloran comes off and Gary Miller replaces him as St Johnstone boss Tommy Wright definitely looks to hold on what he has - a midfielder for a striker.
Celtic fans are beginning to get frustrated, but their side are beginning to turn up the pressure on the visitors with a series of corners.
Actually, it is goalscorer Danny Swanson who has come off for St Johnstone. Manager Tommy Wright is maybe trying to tighten up, although Swanson's stamina has always been his Achilles heel.
Lee Croft is about to come on for St Johnstone, with St Johnstone striker Michael O'Halloran looking injured.
Tom and 20 others: "Well that's put a weasel amongst the woodpeckers." The woodpecker won that won, so maybe the underdog might come out on top here too.
Celtic have made two changes, with Gary Mackay-Steven and Anthony Stokes being replaced with James Forrest and Nir Bitton.
"Two goalkeepers would not have saved that one. Celtic are looking a bit weary and St Johnstone are full of energy and smelling blood. They are high energy and most of the game is being played in the Celtic half."
Steven Anderson misses a great chance to put St Johnstone two ahead. Everyone else fails to get a touch on a corner into the penalty box and the defender volleys wide when he should have hit the target.
St Johnstone goalkeeper Alan Mannus is unsighted but manages to get down to turn wide a low drive from Anthony Stokes as Celtic look to hit back immediately.
On-loan Coventry City midfielder Danny Swanson lets fly with a 25 yard drive that hits the top corner of the net to give St Johnstone a lead they have been threatening in the early stages of the second half.
Efe Ambrose fires a powerful drive at goal, but St Johnstone goalkeeper Alan Mannus holds at the second attempt.
Celtic made a change at the break, with Wakaso Mubarak coming on to replace Adam Matthews. The Ghana international has slotted into the left-back spot, with Efe Ambrose moving across to right-back.
A header from Murray Davidson takes a deflection and over the Celtic crossbar as St Johnstone win a couple of corners.
Gary Mackay-Steven fires wide as the Celtic midfielder does not get enough on his shot.
A dangerous pass back from Jason Denayer straight after the restart almost hands Steven MacLean a chance to open the scoring for St Johnstone, but Celtic clear.
Paul Black: "Interesting to see Johansen in a deeper role tonight. Attacking line-up for Celtic. Could see some goals tonight." Sorry for the delay in posting this Paul. You posted this on kick-off and hopefully your prediction is right in the second half!
BBC Scotland at Celtic Park
"Some St Johnstone players have impressed in individual cameos - Brian Easton, David Wotherspoon, Steven MacLean and Steven Anderson - and the team spent a spell pressurising the Celtic defence. The champions have not been making the most of being stronger on the flanks and are being restricted to lone-range efforts, so the game has become more even."
Dundee United fans might be interested to know that it was 28 years ago tonight that their side beat Barcelona 1-0 at Tannadice in the Uefa Cup quarter final.
BBC Scotland at Celtic Park
"Celtic have been typical bright and incisive, with Stefan Johansen still as influential in an attacking sense despite playing in a deeper role in the absence of Nir Bitton. Leigh Griffiths has been sharp, too, in his movement and shooting. At times, St Johnstone are having to defend in desperation."
St Johnstone make it to the break without conceding and have had occasional moments of threat at the other end. Much for Celtic manager Ronny Deila to ponder at half-time.
Celtic defender Virgil van Dijk heads across the face of the St Johnstone goal, but Murray Davidson nods clear for the visitors.
Shots from Virgil van Dijk and Gary Mackay-Steven are blocked in front of the St Johnstone goal amid penalty claims from the home fans.
