Martin Odegaard knows Arsenal must take the lessons learned from the Newcastle defeat to power them for the rest of the season.
Arsenal was dumped out of the Carabao Cup at the semi-final stage after losing 4-0 on aggregate against a clinical Newcastle side.
A 2-0 home loss in the first leg after the Gunners missed chance after chance, to then another 2-0 loss after again, missing early chances with Martin Odegaard missing a glorious chance after just 18 minutes.
The skipper's shot hit the upright, and Newcastle, within a minute, went down the other end, and Jacob Murphy's strike sealed the tie in the Magpies' favor.
The mountain to climb was big for the Gunners, but the 5-1 win over Manchester City gave some hope to Mikel Arteta's side but that was dashed once Murphy's strike got past David Raya.
The biggest thing to come out of the game was once again, the missed chances and this was painfully clear after Odegaard's shot in the first half, only for Murphy to score seconds later. It is a brutal lesson, but one that Arsenal simply has to learn from.

The main theme over the two legs was Arsenal's lack of a lethal front man, something which Newcastle had in Alexander Isak who tormented the Gunners' backline.
That mean there was an even bigger premium on the Gunners taking their chances in front of goal with the Magpies proving in the first leg to be super clinical.
Could things had been different if the Gunners managed to tuck away some of the chances that they created? Without a doubt, but hindsight is a wonderful thing and Arsenal was taught a lesson in efficiency in front of goal by the Magpies and it was one that will hurt for months to come because there were chances, they just failed to take them.
Now, the Gunners will have a 10-day break in which the squad will travel to Dubai and recharge the batteries which by the looks of it at St. James' Park, were running on empty.
Still with plenty to play for in the Premier League and Champions League, this break came at perhaps the right time for Arteta's thin squad.
But once they return, it will be all gas, no brakes, as Arsenal tries to get some silverware for the first time in years under Arteta.
