Speaking on Sky Sports, Neville said: "Liverpool have dropped points in their last eight games. Liverpool have drawn two in the last three, drawn four in the last eight. Arsenal had a chance to get back closer, they could've gone within five points, yesterday. It's a big blow. A really big blow.
"Questions will start to be asked, because it's that type of season where you think it was up for grabs. Arne Slot has come in as the new manager, [Jurgen] Klopp's left. I certainly felt there would be a drop-off at Liverpool, but Slot has been such a cool customer from day one. He's in complete control.
"Arsenal have become quite rigid, they've become quite turgid at times to watch. This obsession with set pieces, which was overtaking their whole game, exacerbated by this presence of the set-piece coach on the touchline which puts more focus on set-pieces. It's like... no. The freedom's gone a little bit from them.
"I know that they've lost Saka, and I know that they've lost Jesus, and I know they've lost Havertz, which are big blows. I mean, let's be clear, that is a big problem for Arsenal. But I still think you've got to do that job yesterday against West Ham at home."
