Burnley had the audacity to take the lead and City were frustrated.

But then two goals in 94 seconds from Sergio Aguero turned the tie around.

Manchester City wanted to avoid any kind of headlines today and they did that with a scintillating display in the second half.

They are now 32 games, domestically, unbeaten.

Andy Holgate: Bizarre comments from Adam Blaize. Pep has indeed inherited a lot of these players but he’s taken them to a new level. He’s “built” the players into great players or even world class. Look at Sterling and Otamendi. Just look at KDB. That is is Pep’s work. Quite dismissive from Adam to the genius of Pep.

Al, Manchester: Please Adam at 1647: Give Pep some credit. He has spent lots of money but hasn't he coached players to improve and play his way? Sterling,Sane, De Bruyne, Stones. Shall I go on?

Swansea manager Carlos Carvalhal: "Listen I don't have an opinion on the Wolves red card but my staff said it was a clear red. I didn't see it - but I saw our red card.

"It is a typical yellow card, a touch on the back of the player in the middle of the pitch. Instinctive. Everyone felt it was a yellow card. This is a situation I don't want to talk too much about, but that's two games in a row with bad decisions.

"I am very happy about my players. We had a clean sheet, the commitment was good.

"I was only in the market for 24 hours after leaving Sheffield Wednesday but I must tell you that my phone rang a lot. I am pleased about that."

You see a lot of turnover of managers in the modern game. Lifespan as a manager is so short. Sometimes though you do have to point the finger at the players. They played OK today but Hughes needed a strong performance and he did pick a strong side. They didn't deliver.

Geoff Kidd: Never rated Hughes as a manager. All this talk of expansive football and the talent he's brought in, but plan B is always Peter Crouch.

Simon Rigler: Feeling a touch sorry for Mark Hughes. Like many worn out relationships, at the end absolutely everything is going against him. Time for a change for both parties.

Is there no way he can rekindle the flame, Simon?

Mark Davies: #QPRFC, external#bbcfacup, external Why do people call for a winter break? QPR have had the first weekend in January off for the last 23 years and it's not improved our results or players at all.

Karl in Peterborough: What a cracking result for the Posh. Can beat anyone outside the Premier League on our day #MightyPosh

Mike: If Guardiola didn't build those teams who did? Credit where credit is due he's doing a top job

West Brom manager Alan Pardew speaking to Match of the Day: "It was a professional display. We were good in the first half and should have had more goals. Exeter had a good old go in the second half and we defended well. At both ends the display was good.

"It was a great attitude on a sticky, horrible pitch.

"The team has functioned well and I didn't want to lose that rhythm by changing players.

"Of course the first win is important to us as it's been so long since we've won a game. We've won here and now we have to try and win at home."

Sam Lock: GET IN NOTTS! What a result that is and such a great goal to win it, good draw for the 4th Road now please

Anon: I'm Hughes in! I mean, I'm not a Stoke fan but don't think he should go. This is the same Stoke that was 9th three seasons in a row under Hughes and playing great football

Liverpool's Philippe Coutinho is understood to be close to completing a £142m move to Barcelona after staying behind as his team-mates travelled for a mid-season break in Dubai.

More to come on that one - just a bit!

James Stevenson: That’s what the cup’s all about. A brilliant win for Coventry City and their fans. Disarray for Stoke. That could be that for Mark Hughes.

Tom in Kent: Well played Wigan and Coventry but for me West Brom winning a game has to be the shock of the day!

Graeme Poole: How can Villa thrash Bristol City 5-0 one week and then lose to Peterborough the next?!! Even more inconsistent than the England cricket team. #FACup, external#bbcfacup, external

BBC Sport's Ivan Gaskell in Coventry:

It was a cup tie that had everything.

Stoke were under pressure coming into the game and they were under pressure for much of the first half.

Jack Grimmer scored from nothing and Stoke tried everything but their afternoon - and the season - took an even grimmer turn.

Stoke heads are down, but Coventry – what a huge shock.

Marcus Hall
Ex-Coventry defender on BBC Radio Coventry & Warwickshire

Coventry have thoroughly deserved the win since the moment they went 1-0 up. Stoke had a few chances but Coventry took theirs. To a man, they were fantastic and to hold on like they did for the last 25 minutes was fantastic. They put their bodies and heads on the line and made it over the line.

Another upset to report as League One side Peterborough put three past seven-time winners Aston Villa to progress.
