Arsenal bounced back from some poor results prior to the winter break to beat Crystal Palace 5-0 at the Emirates Stadium on Saturday.
The Gunners had gone into the game having lost their last three matches across all competitions to West Ham, Fulham and Liverpool.
But Arsenal returned to winning ways on Saturday, with Gabriel opening the scoring before an own goal from Dean Henderson, with Leandro Trossard and Gabriel Martinelli (x2) also finding the net.
GB News now takes a look at four things we learned from the contest in north London.
Secret weapon deserves credit
Arsenal coach Nicolas Jover deserves credit after Crystal Palace Premier League win

Not every team in the Premier League is great with set-pieces.
But Arsenal are - with both of Gabriel's goals coming from corners.
The Gunners have scored an impressive 13 Premier League goals from set-pieces this season, which is more than any other side in the division.
Credit must go to Nicolas Jover, with Arsenal players responding to his positive methods at the club's London Colney training ground.
Small margins make a huge difference in sport and, if Arsenal keep netting from corners and free-kicks, they'll substantially boost their hopes of Premier League glory.
Henderson gets no backing
Dean Henderson was visibly frustrated after Arsenal's second goal and felt he was fouled by Ben White in the build-up.
And he got no support from Declan Rice, despite the duo previously being team-mates for England.
Rice and Henderson squared up to each other in the aftermath, with the duo exchanging angry words.
And Rice seemed amused by the complaints of the Eagles star, smiling as he walked away to celebrate with the rest of his Arsenal team-mates.
Arsenal had every right to smile, too, with the club now getting their title hopes back on track.
Clean sheet a relief for Arsenal
It's been well-documented that Arsenal have struggled in front of goal during the last couple of months.
But they've also been conceding too many, too, which is why they've fallen behind Liverpool in the race for the crown.
Mikel Arteta will, however, be delighted that Arsenal managed to keep Palace at bay with a diligent and disciplined performance on home soil.
Palace rarely looked like troubling David Raya in the Arsenal goal, despite the Spaniard blowing hot and cold ever since his arrival from Brentford.
Gabriel stood tall but White, William Saliba and Oleksandr Zinchenko all deserve credit for their solid defensive performances as well.
LATEST SPORTS NEWS:
Arsenal still need a striker
Arsenal were too strong for Crystal Palace in Saturday's Premier League clash at the Emirates Stadium

With the January transfer window open, it's clear Arsenal need to splash some cash on a new striker if they're to win the title.
Ivan Toney is one player admired by the Gunners but, at the current moment in time, a deal looks tricky to broker.
Arsenal cruised to victory over Palace but could, and should, have scored more than their five goals such was their dominance.
Gabriel Jesus and Saka missed big chances during the game, while Trossard was also guilty of some poor finishing before he got his goal. On another day, against different opponents, the Gunners could have been made to pay.
Except they weren't and Arsenal fans will be jubilant at seeing their recent losing run come to an end.
When are Arsenal and Crystal Palace next in action?

Arsenal are next in action against Nottingham Forest on January 30, with that match due to commence at 7.30pm.
The Gunners beat the same opponents 2-1 back in August, with Eddie Nketiah and Bukayo Saka both on target.
As for Palace, they're next in action against Sheffield United on the same evening.
Palace won 1-0 in the reverse fixture at Bramall Lane in August, with Odsonne Edouard netting the only goal of the game that day.
