The Blues' 1-0 win over the Reds at the Etihad Stadium sent them back to the top of the table on goal difference, with just two games to play. Should City beat both Newcastle and Queens Park Rangers they will become English champions for the first time since 1968.
"Sir Alex Ferguson has rightly said that the title has slipped away," Neville said on Sky Sports. "But you can only keep going. That's all you can do in football."
And although the destiny of the silveware is now in City's hands, Roberto Mancini's men face a tricky test next Sunday when they travel to Newcastle to take on one of the league's form sides. Nothing, Gary Neville insists, is certain yet.
"All the pressure's now on City," he said. "They play first up at Newcastle so United will know exactly what they need to do [by the time they kick off against Swansea at Old Trafford], or even if they've got a chance."
Neville revealed he also expects Sir Alex to bolster his squad in the summer. "I'm sure he'll improve his squad. I think he has to. He's an honest person and he'll recognise there are areas of the squad he needs to strengthen."
