Chelsea's thrilling Super Sunday draw at Swansea was littered with controversial moments - and Sky Sports pundit Niall Quinn delivered his verdict at full-time.
Diego Costa's first-half opener was canceled out by Gylfi Sigurdsson's penalty after the midfielder was tripped by goalkeeper Thibaut Courtois.
Leroy Fer then put Swansea in the lead - with Chelsea's players complaining of a foul on Gary Cahill in the build-up - before Costa equalised with an overhead kick that might have been deemed dangerous play.
Quinn also had his say on the decision of Swansea boss Francesco Guidolin to substitute defender Neil Taylor on 41 minutes instead of waiting for half-time.
Watch the highlights above and read on for the expert verdict...
'The referee was right to award Swansea a penalty… and right not to send off Thibaut Courtois'
Incident: Sigurdsson chased a long ball over the top and Courtois ran to the edge of his box to clear. The goalkeeper misjudged the flight of the ball and was forced into a lunge on Sigurdsson. He did not get any of the ball and brought down the Swansea forward.
QUINN'S VERDICT: "The 'keeper is in a good position, but he mis-reads the curve on the ball. It looks when he is running that he is going to get it, but it curves away from him and Courtois is in trouble as it bounces away from him. He is 18 inches away from making a good, clean tackle, but the red card rule has changed now. It was a genuine effort to play the ball, it wasn't just pulling down someone to stop a goal. As excited as everyone got in the stadium hoping to see a card, the referee got that one absolutely right."
'Swansea's second goal should not have stood'
Incident: Cahill was caught in possession by Fer, who stole the ball off the defender before running through on goal and scoring. However, replays indicated the Swansea player tripped his opponent.
QUINN'S VERDICT: "There was no contact on the ball from Fer and that means something must have gone wrong. Cahill didn't slip over, there was a kick with Fer's right boot. He kicks him in the Achilles and any Swansea fans who think that was fair, need to look at the replay. You'll realise Andre Marriner got it wrong. I won't be too harsh on him because at the time we didn't see the foul in real time."
'The referee was right to award Chelsea's equaliser'
Incident: Branislav Ivanovic's shot was deflected into the ground and high into the air. Costa jumped acrobatically to beat Kyle Naughton to the ball with a spectacular overhead kick to bring his side level.
QUINN'S VERDICT: "When it hops up you think a defender will get to that kind of ball. It was hanging up in the air and the boot was high, but Kyle Naughton's head wasn't up against the boot when it made contact. It was at the end of the movement. Had his head been six or eight inches nearer to the ball at the time of contact I think you'd have had a loud appeal - but none of the Swansea players complained."
'Francesco Guidolin probably should have waited until half-time to substitute Neil Taylor'
Incident: With Swansea trailing in the first half, Guidolin decided to change his system from 3-5-2 to 4-4-2 and replaced Taylor with Modou Barrow. TV pictures showed Taylor unwilling to shake hands with his manager and complaining that he should have waited a few minutes to make the change at half-time. Guidolin apologised after the game, admitting it was "a mistake".
QUINN'S VERDICT: "It has to be said that in the couple of minutes after the change was made, Costa missed a glorious chance so it didn't automatically settle them down and they didn't suddenly appear to be a better team. Once he got them in at half-time that changed and they looked better in the second half. What I like is he cares about his player and he diffused the situation immediately in his post-match interview. It's worth reminding Neil Taylor he wasn't playing badly, he was sacrificed. OK, it happened in front of the crowd and yes, he probably should have waited for half-time."
