The roof of the City Ground was so nearly at risk!

Leicester fail to properly clear a free-kick into the box and Forest keep the attack alive, forging a chance for Keinan Davis in the box that he smashes against the corner of the goalframe.

Great effort, and so, so close to the opener!

The movement of some of the Foxes players is a real issue for Forest. Some of it is very smart and very tough for the Championship side to track.

It is Bryce Samba who does the heavy lifting, leaving his line to punch the free-kick away.

Leicester have a free-kick wide right in the Forest half. It is Youri Tielemans fouled. The home fans do not agree, unsurprisingly.

More work for the Forest defence.

Harvey Barnes is twisting and turning, and Joe Worrall gets taken to the cleaners. Outstanding play.

Harvey Barnes looks a threat every time he gets on the ball. He takes Joe Worrall apart down the left and then fires in a low cross that is just ahead of Ademola Lookman at the far post.

Djed Spence offers so much going forward. He needs to also be mindful of what goes on behind him too.

Djed Spence - on loan from Middlesbrough - is another player a lot of clubs have been watching. He drives forward down the right and sends in a cross that Leicester are just able to prod away.

Nottingham Forest winger Brennan Johnson is regarded as one of the best young talents in the Championship, with his club rejecting an £18m bid from Brentford in last month's transfer window.

The 20-year-old Wales international, who has seven goals this season, has had a couple of chances to make his mark on this match already.

However, he fired a free-kick into the wall from just outside the penalty area and then failed to capitalise after Foxes defender Daniel Amartey had gifted him the ball 40 yards from goal.

Clever by Ademola Lookman. He gets away from his man and it's fortunate that hasn't gone in.

Leicester's second corner leads to a stint of pressure that Forest do well to see off.

Close!

James Maddison drives his corner low to the edge of the box and Ademola Lookman's strike deflects wide off a Forest player. Could have gone anywhere.

At every opportunity Leicester are trying to get forward. It needed a bit more composure by Harvey Barnes but he's a player who needs watching and he impresses.

Leicester have another corner. They've taken a bit of control now.

Leicester's quality is starting to emerge. Harvey Barnes and Luke Thomas link up well down the left again but the former's touch lets him down and the ball bobbles away from him for a goal-kick.

Those two Foxes attacks have just given Forest something to think about after their positive start. Few little nervous moments at the back for the home side.

Gripping stuff so far.

Really positive from Forest. They really go after teams early but Leicester work it really well down the left hand side. The full-backs are going to tested. That should have been a better finish by Iheanacho.

The atmosphere is great. Constant, high-volume noise.

Forest are forced to concede a corner as the Foxes continue to look threatening.

Oh, a big miss!

Leicester work it really well down the left and Luke Thomas sets up Kelechi Iheanacho in acres of space in the box. The ball is slightly behind him but he still should hit the target. Instead he smacks it wide.

Let off for Forest.
