When Gary Neville starts sounding off, you know something's happened that won't sit well with Liverpool.
Gabriel's 96th-minute winner for Arsenal against Newcastle on Sunday had the former Manchester United player all fired up on Sky Sports, immediately declaring that this turnaround could significantly impact the Premier League title race. There's no denying that Arsenal's last-gasp heroics at Tyneside will inject a dose of confidence into Mikel Arteta's squad, much like Liverpool's even later game-winner at the same venue last month.
However, there won't be any panic at Anfield just yet over this result or indeed Saturday's 2-1 defeat at Crystal Palace, Liverpool's first setback in a season that until now had been flawless, perhaps even too flawless given the number of late winners.
A twist in the tale was likely inevitable at some point, but to endure two in one weekend will undoubtedly sting, despite Virgil van Dijk's call for cool heads following the Selhurst Park loss.
The Reds will regroup, recall their two-point lead at the top of the table, and carry on regardless. But they'll now have to deal with the increasing chatter from London, and indeed from Neville's corner of Manchester.
The season is still young, but the Gunners clearly have momentum now, and what's more, they have excellent opportunities to keep it going.
Having already faced off against Old Trafford, Anfield, and St. James's Park this season, as well as hosting Manchester City, Arsenal's Premier League schedule for the next month appears to be quite favorable.
The Gunners are set to play West Ham (home), Fulham (away), Crystal Palace (home), Burnley (away), and Sunderland (away) in their next five top-tier matches before a north London derby against Tottenham on 23 November after the final international break of 2025.
In contrast, Liverpool will be playing Chelsea and Manchester City in its next five Premier League games, as well as hosting Manchester United, who, despite the jokes, managed to secure a draw on the team's last two visits to Anfield.
A trip to Brentford and a home game against Aston Villa won't be easy tasks either.
With pundits like Neville keen to fuel the title race, it's certain that Arsenal's chances will be discussed extensively over these next few games, but they are indeed very winnable ones for Mikel Arteta and his highly skilled, resilient squad.
Liverpool is now going to face even more scrutiny and constant reminders that Arsenal is hot on its heels.
In fact, the Gunners could temporarily take the top spot if they defeat West Ham next Saturday before Liverpool face Chelsea.
Last season's Liverpool title procession wasn't enjoyable for many, including Neville, so you can expect Arsenal's upcoming weeks to be driven by goodwill and a narrative sense of destiny.
The Reds are maintaining their composure for the time being, but as the clamour intensifies, their response must become more decisive. The competition is already heating up.
