Half a chance for Wilfried Bony...but he is denied. The ball drops nicely to the Man City substitute's feet about 18 yards out, he blasts it goalwards, only to see Wes Morgan block.

The Foxes skipper flung himself in front of the ball like Kevin Costner flung himself in front of Whitney Houston in The Bodyguard. Top defending.

This is a palm-stinger! Leicester win a free-kick on the right corner of the away box, Christian Fuchs hammering a rising shot towards goal. But Joe Hart is wide awake in the City goal to block. Fuchs has got a left peg like Stuart Pearce!

The initiative is firmly with Manchester City now.

Their midfield is providing a solid platform. Yaya Toure and Fernandinho are maintaining possession better than N'Golo Kante, Danny Drinkwater and Gokhan Inler.

Toure and Fernandinho have completed 82% and 83% of their passes respectively. 

Will we get a winner?

Time for another City change - a Spanish-themed change in fact. On comes right winger Jesus Navas, off goes his international team-mate David Silva. Blues boss Manuel Pellegrini will be hoping Navas' pace and width can stretch the home defence.

End to end stuff - can someone become a hero? Not Jamie Vardy on this occasion. The Leicester striker peels off to the left channel, meeting a brilliant diag from Danny Drinkwater, but the angle beats him. Comfortable save for Blues keeper Joe Hart.

Oh Wilfried Bony! He might have 28m pound of muscle but he hasn't got £28m of football talent. The City substitute slashes his size 10 at a cross from the left...skies it.

Tom in Wiltshire: Nathaniel Clyne to Liverpool. Great signing. Not often you see an English man live up to the inflated price tag. Quiet and consistent.  

Kevin from Lytham St Annes: United Keeping De Gea is the best signing and that from a City fan. If not Cech to Arsenal.  

Technically Manchester United didn't buy David De Gea this season, but we'll let you off this time, Kevin, being as it's the festive season.

Time to update you with the latest from the Championship. 

Fulham look on course to record a comfortable home win, leading 3-1 against Rotherham with Alexander Kacaniklic netting in the 59th minute to turn the screw. 

The other games are going a little like this: 

Brighton 0-1 Ipswich 

Cardiff 1-1 Nottingham Forest

Leeds 1-1 Derby

Here comes that Leicester change - finally. Maybe the fourth official couldn't work his electronic board quickly enough.

Anyway...striker Leonardo Ulloa comes on for midfielder Gokhan Inler as Leicester go back to a more-familiar 4-4-2 formation. 

Seconds after Aguero is hooked, Man City almost break the deadlock. Nicolas Otamendi escapes his marker to meet Kevin de Bruyne's right-wing corner - but Kasper Schmeichel is equal to it. The Leicester keeper flings himself left to push clear.

"Aguero didn't look sharp. It's a double-edged sword, if you're not fit you shouldn't play but you can't get fit without playing games."

Aguero, with 29 touches, saw less of the ball than any Manchester City player. On the plus side, he completed 93% of his 15 passes.

Those changes are happening. First off is Sergio Aguero, who is replaced by Wilfried Bony. Aguero has not quite been himself tonight as he continues his return from injury...

"He just throws his gloves at the feet of the referee does Sergio Aguero."

Both benches are a hive of activity. Looks like Leonardo Ulloa is coming on for Leicester, with Man City's Wilfried Bony also stripping off.

Sergio Aguero - the man likely to be hooked - thinks he should have a penalty after a strong challenge from Gokhan Inler. Think Inler might have got away with one there...

"That's the best move Leicester have engineered.  Lovely ball in from Mahrez, Albrighton cant quite get his bearings on the turn and he skews it wide."

As our man Phil McNulty alludes to, there is a cracking pace to this match. Another chance for Leicester after Riyad Mahrez's shows brilliant vision to pick out Marc Albrighton's central run. But the ex-Villa man can only drag his shot across the far post.

Both sides really going for it at the start of the second half and have both had chances.

The tempo has increased and the game has opened up - get the sense a goal is coming - and Leicester City's vociferous fans are convinced it is coming for them.

One Leicester fan is holding up a banner saying 'We are staying up'. I think I've got a better chance of winning the Euromillions than the Foxes going down now.

Huge applause for Foxes defender Robert Huth as his diving header back to keeper Kasper Schmeichel averts any danger.

Who have been the best and worst Premier League buys this season? Here's a selection of your answers to tonight's debate.

Penalty?! That's what the 3,000 or so away fans shout for in unison. Danny Simpson slides in on Sergio Aguero close to the penalty spot, he doesn't get man, but does he get ball with his hand? Possibly. Was it intentional? No chance.
