Richard: SMALLING IS THE BEST ATTACKING DEFENDER WE'VE EVER SEEN.

Dennis: Smalling makes it up wow.

PJ: What a game! Chris Smalling redeeming himself there with that lovely finish! That's how we do it...UNITED!!!

City now need TWO goals if they want to clinch the title today.

They have 17 minutes to find them.

Fabian: What did Mourinho tell these players at halftime? Wow what a comeback?

Chris: It really isn't a secret City's defense is iffy the trick is getting at them and being bold enough to take that risk

Here come the cavalry.

No Silva lining for City? Both David and Bernardo are hooked.

On come Kevin de Bruyne and Gabriel Jesus.

Wow. Unbelievable. What are we seeing? United were embarrassing in the first half and now they are 3-2 up. Great finish from Smalling.

I've never seen a better transformation from a side.

I still can't believe the way this second half has gone. I'll be honest, at half time I started my match report, all based on City winning the title.

Now it is a piece of paper I can put in the bin on my way out. As it stands United will deny City from winning the league this evening.

It could have been 6-0 at half-time...

City want to find their rhythm again but their smooth running machine has caught a glitch and they are finding it difficult to get back to full working order.

Remember, City WILL NOT win the title today if the scoreline stays the same.

Feroze: In the underground Piccadilly line from Heathrow to central London. Coverage obviously broken. Into the tunnel at 2-0. Out at 2-2. What's going on??? :)

Ilkay Gundogan is the City player to strike the free-kick, over the wall, but over the crossbar too.

David Silva ran the show in the first half but it has been a different story in the second.

He does get on the ball close to the edge of the box, but is brought down by Nemanja Matic.

Free-kick for City in a very promising position.

The only debate at half-time seemed to be how many Manchester City would win by and what a shame it was that the Premier League trophy was not going to be presented today.

Now this.

Manchester United, utterly outclassed and over-run in the first half, are suddenly brimming with confidence,

The mood might have also changed among those watching from Liverpool too. From fearing the firepower shown by Manchester City they will be eyeing the defensive frailties on show since half-time.

Coolisha: Take my words back!! Pogba can color himself fluorescent blue if he can score one more.

Ken: This is why we love football. Totally unpredictable and absolutely beautiful.

Little on large.

Raheem Sterling somehow sends Romelu Lukaku tumbling to the deck with a trip and is given a yellow card for the challenge.

Paul Pogba and Alexis Sanchez have really stepped up for United, when their team-mates needed them the most.

Now can they finish the job?

Serge: Sterling's wasted chances coming home to roost.

Andrew: To be fair, City switched off for a couple of minutes, probably thinking that the game was over. It's clearly not.

Have these sides swapped shirts at half time??

It is City who look all over the place now, giving away possession.

United break clear through Alexis Sanchez, but then Jesse Lingard's low shot from outside the box drift a yard or two wide.
