Yaya Toure scored a double to put Manchester City on course for the title - but immediately warned of some hard work ahead.
Toure's brace earned an impressive 2-0 win at Newcastle meaning, that barring any mathematical miracles, a win over QPR next weekend will earn Roberto Mancini's men the championship.
The Ivory Coast midfielder, though, was not prepared to look too far ahead, despite acknowledging the significance of the result.
"It's not finished," he told Sky Sports 1. "We have one game left and we have to be careful as QPR are fighting to stay in the Premier League.
"We have to continue to work hard and believe. The manager told me to deliver because it was an important game.
"Newcastle are a physical and strong team, but we need to keep improving. This is brilliant for us, though."
