After starting December with defeat by Aston Villa, they were far from convincing as they beat Wolves, Everton and Brighton by narrow margins.
But the Gunners ground out vital results and they answered any lingering doubts over their title credentials with an emphatic 4-1 home victory over Villa on Tuesday.
It not only kept Unai Emery’s in-form side at bay in third place, it served as a powerful statement to any team hoping to derail their trophy ambitions.
Arsenal head into 2026, and the second half of the campaign, at the top of the league – five points clear of second-placed Manchester City, with Villa a further point behind.
“Arsenal doing what they did to Villa tells you where they are,” former Aston Villa striker Dion Dublin told BBC Radio 5 Live.
“It’s all going right for them because everyone is contributing – the manager, the players, the staff.”
Speaking on Match of the Day, ex-England midfielder Danny Murphy added: “Arsenal’s performance was a big statement. It was powerful, full of quality and showed their strength in depth.”
But, with a history of letting the title slip from their grasp following three successive runners-up finishes, can Arsenal finally make it count this season and be champions for the first time since 2004?
Arsenal have been here before.
They entered 2023 in top spot, five points above Manchester City.
But the tables turned and Pep Guardiola’s side were the ones holding the trophy at the end of the season after finishing five points clear of the Gunners.
It was a similar story in the 2002-03 season, when they finished five points behind Manchester United having been top at the end of December.
In fact, of the previous six occasions Arsenal have ended the calendar year in first place, they have only gone on to win the Premier League once – back in 2001-02.
