Arsenal closed gap on Premier League leaders Liverpool to two points thanks to Gabriel's 96th-minute winner at Newcastle which will send a message to The Reds that manager Mikel Arteta and his side will not let up.
The victory saw Arsenal climb back up to second in the Premier League table and they now sit two points behind Liverpool who face Chelsea on Saturday afternoon.
Speaking on his Sky Sports podcast, Neville said the victory sent a clear message to Liverpool who may be worried about letting their lead slip.
“Mikel Arteta has got a brilliant squad. He’s got a brilliant squad, I think he’s got the best squad in the league and maybe the best team in the league and I say that quietly because Liverpool are excellent.
“There’s only two teams who can win this league – Liverpool and Arsenal – I don’t think anyone else can. So I think it’s a big moment. It’s only September and it’s ridiculous to be speaking like this as someone who experienced title races.
“But what you’ve got to do is send out some calling cards and some clear messages that you’re there in the title race and I think that’s what Arsenal have done today.
“A week ago the glass was half empty, now it’s more than half full. Liverpool lose, Arsenal win in stunning fashion.
“You shouldn’t have swing weekends this early. But the Liverpool players sitting at home watching this will perhaps sink slightly.”
Strikes from Mikel Merino and Gabriel Magalhaes allowed Mikel Arteta's side to secure all three points on Tyneside in what was a much needed late victory for the North London side. All eyes now turn to this weekend as more dropped points for Liverpool could mean Arsenal jumping in first place.
