A glimmer of space opens up for Daizen Maeda as the Celtic winger cuts in from the left, but he drags his shot well wide.

The party vibe in the Celtic sections at kick off is turning into one of growing frustration.

Ange Postecoglou's side are not themselves.

A shake of the head from Ange Postecoglou as a stray pass from Matt O'Riley rolls straight out of play.

Both sets of fans turn on referee John Beaton as he gets in the way of a Greg Taylor pass.

Drop-ball to Celtic, but it soon ends up in the arms of goalkeeper Mark Ridgers, who may well have expected to be a lot busier.

Celtic haven't been able to get the speed in their passing or movement. Inverness Caley Thistle have closed up those gaps, they've not allowed Celtic to play at the speed they would like.

But knowing Celtic, that change of pace could come in an instant.

It's been a real good start for Caley Thistle. They look well organised.

There's clearly a plan there, They've had a month to work on it, so maybe we shouldn't be too surprised.

Suddenly the Championship side are caught short at the back but Jota takes too long on the ball to get a shot away and his back-heel fails to find Kyogo, who slips on the turf.

Twenty minutes in. So far, so good if you're a Caley Thistle fan.

Despite offering nothing in attack, their team looks well organised out of possession. They're being helped by some slack passes from their opposition.

Some light groans starting to come from the Celtic support around us...

The thing with Iwata playing a centre-half, he's so comfortable on the ball that if there's no pressure on, he will find the passes.

But, Inverness have been well organised, they've kept a good shape. They've made Celtic force the passes.

The first shot of the game spins high and wide off the turf as Matt O'Riley throws himself at a loose ball in the Caley Thistle box.

Billy Dodds will hit his daily steps goal today. The Inverness boss has marched along the length of his dugout countless times so far.

He'll be feeling all sorts of emotions.

Hampden is a riot of colour and noise, but there's not much going on in terms of action on the park.

Another roar of approval from the Inverness fans as Sean Welsh times a crunching challenge on Greg Taylor to perfection.

Is this a sub warming up for Caley Thistle already?

Three overhit passes from Celtic have been greeted with big cheers from the Caley Thistle fans.

They'll be hoping there's more to shout about than that throughout the game. Their team doesn't look too fazed so far.

Inverness don't seem nervy, and they're certainly not sitting back.

They've got three up top there and they're trying to make sure that Celtic can't dominate proceedings in the way we know they like to.

Celtic are playing some brilliant football. It's a huge task for Inverness Caledonian Thistle today. They'll believe they can cause an upset.

In order to do that, every single player has to be at their absolute maximum, and hope Celtic have an off day. When Celtic get going, they are relentless.

They've set up interestingly, with Billy Mckay on the left and Nathan Shaw through the middle.

Celtic are already enjoying the lion's share of possession but there has been nothing to trouble ICT goalie Mark Ridgers yet.
