Mothers across Tyneside have been warned. Thousands of Geordies won't be home for tea on March 16. They are going to Wembley.

Seven decades after lifting their last major domestic trophy, Newcastle have reached a second Carabao Cup final in three seasons following a superb 4-0 aggregate win against Arsenal. If last month's landmark first-leg victory at the Emirates was impressive, well, this was one of those nights at a febrile St James' Park.

To think Gabriel Martinelli had talked up the prospect of rampant Arsenal scoring 'three, four or five goals' at St James' a few days ago. There was a time when that happened. Not anymore.

You only had to glance up at the Arsenal fans heading for an early exit in the 71st minute to realise that. On the anniversary of Newcastle's astonishing comeback from 4-0 down, in 2011, there was no chance of history being flipped - and the travelling support knew it.

By that stage, Geordies were urging their side to take the proverbial. There were even taunts of 'Mikel Arteta - it must be the ball!' after the Arsenal boss' previous moans.

You would have known Newcastle captain Bruno Guimaraes had felt 'very anxious' before this 2-0 semi-final second-leg triumph. This side did not play with crippling nerves. Quite the opposite, in fact.

Newcastle had already taken a huge step towards reaching the final, before a ball was even kicked on Wednesday night, but there was no danger of the black-and-whites going into protection mode. Not in this bear pit. 'Get into them!' screamed the Wor Flags banner in the Gallowgate. Newcastle certainly did that.

In fact, it was Newcastle who looked like the side looking to desperately overturn a two-goal deficit in the opening stages. Newcastle may have fielded an extra defender, but Eddie Howe's team went man for man and pressed high from the off.

Having struck first through Jacob Murphy, Newcastle's bold approach paid off for the Magpies' second when a supposed centre-back in Fabian Schar sprinted the length of the field to pick Declan Rice's pocket outside Arsenal's box and set up Anthony Gordon. How often do you see Rice forced into an error like that? No wonder Arteta admitted his side had been 'unsettled' on a night aggressive Newcastle won 53 duels.

There was an edge to Newcastle, epitomised by the returning Kieran Trippier, who at one point stood over Gabriel and got in his face after the towering Arsenal defender went down softly following a shove to the back. When Gabriel then lashed out, Trippier stood his ground.

Arsenal are not necessarily used to that. This is an Arsenal side who 'try and bully you', in the words of Gordon, but the forward vowed 'that was never going to happen at this place'. Those words were echoed by Howe.

"We're always competitive," the Newcastle boss said. "You have to go up against your direct opponent and you have to be in their face. It was not necessarily a direct order to be aggressive, but we had to stand our ground and try and win our battles. If that means a physical confrontation, we back ourselves to mix it with them."

Newcastle mixed it, all right. Although losing a powerhouse like Joelinton to injury before the game was a blow, a switch to 5-4-1 gave Newcastle added solidity at the back after Sven Botman came into the side and this was a well-earned clean sheet. The numbers don't lie in that regard; the Magpies made 43 clearances and won 21 tackles.

Arsenal may have hammered champions Manchester City at the weekend, but the Gunners were limited to just a handful of shots on target despite dominating possession and territory. Newcastle even held firm from set-plays against the set-piece masters.

The tone was set from the get-go at a rocking St James'. There were less than four minutes on the clock when Gordon hooked the ball forward to send Alexander Isak racing through on goal and the red-hot striker lashed home to send Geordies wild. It was the perfect start. Only VAR intervened and found that Isak was in an offside position.

It was a lifeline for Arsenal, but the Gunners did not take it. Just a few minutes later, Martin Odegaard fired wide from close range - and Newcastle made the visitors pay with their next attack.

Martin Dubravka launched the ball forward and Isak expertly held off William Saliba before playing a one-two with Gordon. It was a rerun of the disallowed opener but, this time, Isak beat the offside trap only to then see his venomous effort bounce off the upright. Murphy, though, gambled and was first to the rebound to volley Newcastle in front. This time it counted.

The first goal in a game is always crucial, but in a tie like this? It was priceless. Newcastle suddenly found themselves 3-0 up on aggregate.

After grabbing the opener, resilient Newcastle showed the other side of their game as Arsenal struggled to find a way through a black-and-white wall. On the rare occasion Arsenal managed to do so, Newcastle had a goalkeeper in Martin Dubravka to bail them as the Slovakia number one did midway through the first half.

Lewis Hall's attempted clearance was straight to Odegaard and the Arsenal captain knocked the ball forward to Kai Havertz. The Germany star pulled the ball back across the box to Leandro Trossard, but Dubravka got down to make the save. Remarkably, it was as close as Arsenal came to scoring all game.

In fact, it was Arsenal's defenders who looked nervous. Gabriel's weak header back to Saliba was bad enough early in the second half, but the centre-back was far too casual as he tried to control the ball and Gordon pounced. Gordon, having spotted David Raya off his line, attempted an audacious effort from 30 yards that sailed wide.

The press did not pay dividends on that occasion, but it soon did. Raya tried to play out and go short to Rice, but the aggressive Schar read the situation and got to the ball ahead of the England international in the 52nd minute. Schar hooked the ball into Gordon's path and the forward fired past Raya to double Newcastle's lead on the night.

That was the cue for black and white scarves to rain down from the stands. Gordon picked one up and swung it above his head. Newcastle are on their way to Wembley. What will be, will be.
