Alfredo Morelos smashes an angled shot through the legs of Jeremie Frimpong and it seems to take Fraser Forster by surprise, with the Celtic keeper beating the ball down between his own legs. The ball is loose inside the six yard box and full-back Jonny Hayes get there first to hoof it to safety.

We had fireworks before kick off and we've been treated to some fireworks on the pitch, with Rangers starting like a rocket.

Yet another Rangers. It nearly falls for Connor Goldson after the ball is held up in the wind but a defender in green and white is able to hack it away.

Rangers' Ryan Jack lets fly from 25 yards and it looks like the shot is destined for the top corner before Fraser Forster stretches his huge frame to claw the ball away.

A first class save.

Celtic winger James Forrest squeezes a pass into the penalty area from the right and it rolls to Lewis Morgan, who slashes an ambitious first-time effort way wide.

Another Rangers corner. Filip Helander is the target but the Swede's header on the stretch is easily cleared away by Christopher Jullien.

Celtic get forward for the first time but their momentum is broken when Borna Barisic stops Jeremie Frimpong in his tracks with a wonderful slide tackle.

It's all Rangers right now as Borna Barisic swings in a cross from the left. Scott Arfield gets to it first but the header lacks conviction.

Connor Goldson again. The Rangers defender is picked out by a James Tavernier free kick but the header is way off target.

Good pressure from Steven Gerrard's side.

Corner to Rangers. Filip Helander gets his head on James Tavernier's delivery but the ball shoots high up into the sky before Fraser Forster punches clear.

A second corner. This time Connor Goldson attacks it and sends his header high and wide.

And away we go.

The teams are out. It's noisy at the national stadium. Very, very noisy.

There are a few smoke bombs going off too, making it look like a heavy fog has descended.

Former Old Firm strikers Ally McCoist and Chris Sutton take turns at showing off the cup to both sets of fans at a rainy Hampden but are largely ignored.

Not long to go now...

Asked by BT Sport if reports he had signed a new contract at Rangers were true, Steven Gerrard said: “It’s not important right now. All our attention is on the next 90 minutes and beyond. I’ll speak to you on that if and when needed.”

You can make your own mind up on that one...

Rangers manager Steven Gerrard tells BT Sport midfielder Steven Davis "had no chance".

"He's got a calf problem and will probably miss two or three games," he explains. "Barisic has pulled through, he's in great form so that one was a no-brainer."

On the match, Gerrard says: "You've got to defend well. Celtic have got good players, especially their front four who have got good movement. It's important we try and nullify their threats.

"And when the game presents itself for us to go and show how good we are from an attacking point of view we need to go and execute. We've got good players as well. It's important we play the game rather than the occasion. We need to get the best Rangers today."
