Cian Hayes has been lively since he's come on.

He's a good option to have to come off the bench late in games. He can create something out of nothing.

Peterborough now make another change, with Abraham Odoh making way for Kyrell Lisbie.

Matthew Turner comes to the rescue for Cardiff City now, making a fine reaction save to stop Gustav Lindgren from snatching a late equaliser.

Lindgren does superbly well to keep control of the ball in the area, and fires goalward on the turn.

The Bluebirds' debutant goalkeeper has made a great first impression.

It should really be game over right now, but Cardiff substitute Callum Robinson drags his shot wide and can only find the side-netting.

He was well picked out in the area, and possibly had more time than he thought to pick his finish.

Peterborough full-back Harley Mills finds his way into the book, after getting a fist full of his opponent's shirt as he tried to get away.

The free-kick is well defended, but the danger isn't completely gone as Cardiff push for a third goal.

The TV cameras have picked out legendary former Manchester United manager Sir Alex Ferguson in the stands.

He is, of course, in the Welsh capital to watch his son's side Peterborough United in action.

Can Posh deliver for their boss Darren Ferguson with a smash and grab finish?

And into the final 10 minutes we go.

That latest save from Nicholas Bilokapic means Peterborough are still in with a chance of taking something from this game late on.

Not for the first time today, Nicholas Bilokapic makes a big save for Peterborough.

This time it's a diving effort to keep Ollie Tanner out after he met a clever backheel pass from Joel Colwill in the area.

The Peterborough changes bring a response from Cardiff boss Brian Barry-Murphy, who brings Chris Willock and Callum Robinson on for Yousef Salech and Cian Ashford.

They were two brilliant goals from Cardiff and both came at important times.

Now I'm intrigued to see how Cardiff are going to play at 2-1.

Peterborough United boss Darren Ferguson goes for a quadruple change in an effort to find a way back into the game.

Oscar Wallin can't continue and he is replaced by Geroge Nevett.

Meanwhile, Cian Hayes, Gustav Lindgren and Ryan De Havilland come on for Bradley Ihionvien, Donay O'Brien-Bradley and Declan Frith.

There is a break in play that allows both sets of players to take on some water.

Cardiff's Yousef Salech and Peterborough's Oscar Wallin get some treatment.

Yousef Salech gets claps of encouragement from the stands at Cardiff City Stadium.

The striker has looked alert all afternoon, and the latest attempt to find him is a long ball that just skips ahead of him and through to the Peterborough goalkeeper.

Joel Bagan is the latest Cardiff City player to go into the referee's book as he makes a clumsy tackle on Brandon Khela.

Cardiff have dominated this second half and are well in control of this game.

You just feel that Posh need to build something now. They haven't really got forward and haven't really seen much of the ball.

Cardiff City boss Brian Barry-Murphy turns to his bench for the first time, as Dylan Lawlor is replaced by Jesper Daland.

This new-look, youthful Cardiff City are playing some silky, clinical football right now.

It has taken them less than 15 minutes of the second half to turn this game on its head.

Ronan Kpakio whips it first time and it goes over the goalkeeper and in off the crossbar.

What a turnaround.

I think Nicholas Bilokapic will be dissapointed with that. He gets a hand on it but he'll feel he could have pushed that over the bar.

"We are top of the league," chant the Cardiff fans, showing an understanding of the goals scored rule that places them above Luton as things stand.
