Stones grabbed the winner by sweeping in a finish from Riyad Mahrez's pass. "Some days it doesn't come off for the forwards, and today me and Ruben chipped in," Stones said. "That's part of us being such a good team and the collective. In big games or important games, everyone chips in, maybe sometimes the person you don't expect."
Manchester United and Leicester are tied on points as City's nearest rivals, and both played this morning.
It was a significant day at the other end of the standings, as well, with Brighton somehow contriving to lose at West Bromwich Albion 1-0 in the most mystifying way possible.
Brighton probably thought losing to Crystal Palace 2-1 on Monday after allowing just two touches in its own box would end up being its most unfortunate of defeats this season. They were wrong.
Five days later, Graham Potter's side missed two penalties and also saw a goal from a free kick ruled out because of the incompetence of referee Lee Mason amid farcical scenes at The Hawthorns.
Lewis Dunk curled in a quickly taken free kick from the edge of the area a split second after Mason blew his whistle for play to restart. However, Mason blew for a second time just as the ball was crossing the line, having seen that West Brom goalkeeper Sam Johnstone was still lining up his defensive wall and wasn't ready for the free kick.
Mason initially awarded no goal, then reversed his decision. As chaos ensued — with players from both teams surrounding the official — the increasingly beleaguered Mason was advised by the VAR to view the incident on the pitchside monitor and, after a lengthy delay, returned to the field to again disallow the goal.
"It's embarrassing, it is a horrendous decision," Dunk said. "I said to the ref, 'Can I take it?' He blew his whistle and I took it. I don't think he knew what he was doing."
As it was, Kyle Bartley's goal earned West Brom only their third win of the season and moved the next-to-last team to within eight points of safety.
At the end of a miserable week, Brighton were just four points above the relegation zone having played one game more than third-to-last Fulham.
Newcastle are level on points with Brighton and also at risk of being caught by Fulham after being held by Wolverhampton to 1-1.
Aston Villa moved to within four points of the European qualification positions by beating Leeds 1-0 thanks to Anwar El Ghazi's early goal.
