Arsenal manager Mikel Arteta has agreed a new three-year contract with the club.

The Spaniard was set to be out of contract at the end of the season but is now expected to stay until 2027.

The Gunners appointed Arteta, who had been working as a coach under Pep Guardiola at Manchester City at the time, to replace compatriot Unai Emery as boss in December 2019.

He led Arsenal to victory in the FA Cup final at the end of the 2019-2020 campaign to claim his first major trophy as a manager.

Arteta's new deal is expected to be confirmed before Sunday's north London derby at Tottenham.

Arsenal have finished second to Manchester City in the Premier League in the past two seasons as the 42-year-old tries to steer the club to their first top-flight title since 2003-04.

After three games this season Arsenal are fourth, having won their first two matches against Wolves and Aston Villa before being held to a draw by Brighton.

A former midfielder, Arteta made 150 appearances for the Gunners during his playing career and also captained the side.

Arsenal have successfully become a force again under manager Mikel Arteta, and a new three-year deal represents a firm backing that he is the man to end the club's wait of more than 20 years for a Premier League title.

It felt like there was little chance he would leave when his contract expired next summer, given the relationships he has built internally and the reassuring calm with which he spoke when discussing the deal.

But previous links to Paris St-Germain and Barcelona perhaps showed the need to tie down Arteta.

The whole machinery at Arsenal behind the scenes is behind both Arteta and sporting director Edu, who have found a way to be competitive against the Manchester City juggernaut - running them close to the title last season.

They also went close in the 2022-23 campaign, but it is now time to take the final step.

After signing Raheem Sterling, Mikel Merino and Riccardo Calafiori the Gunners have again strengthened, though question marks have remained over whether they should have signed a striker.

This is a manager, squad and backroom staff seemingly now capable of winning the biggest titles in England, and it is perhaps symbolic that a new deal comes before a north London derby against Tottenham.
