Premier League round-up: Man City draw, Sunderland record first win
Pep Guardiola fails in his attempt to build a lead at the top with just a draw against Middlesborough as Liverpool, Arsenal and Tottenham all play tomorrow.
Sergio Aguero's 150th City goal looked to have sent his team three points clear, but De Roon brought the Etihad Stadium back to earth following Tuesday's brilliant 3-1 win over Barcelona in the Champions League.
"We did absolutely everything to win the game," said Guardiola, whose side have drawn their last three home league games 1-1 following previous stalemates against Everton and Southampton.
"We controlled the game and in the last minute we concede a goal. It is a pity. We did a lot of good things and tried to win the game.
"It is a miss because we have dropped six points in the last three home games, but we are still there. We have to move forward."
Looking for leaders
City's slip-up means Chelsea can surpass them if they overcome Everton in Saturday's late game, while Arsenal and Liverpool -- both just a point off the pace -- will also have designs on top spot.
Second-place Arsenal tackle Tottenham Hotspur in Sunday's North London derby before Liverpool entertain Watford.
Sunderland remain bottom, below Swansea City on goal difference, but manager David Moyes belatedly has a victory to his name following a hard-fought success at Bournemouth's Vitality Stadium.
"It is a big relief," Moyes told Sky Sports. "We owed the supporters the victory. They have kept with us.
"We needed a win, but it is only one. We need a few more."
Around the league
There was late drama at Turf Moor as Burnley withstood a Crystal Palace fightback to prevail 3-2 courtesy of Ashley Barnes's 94th-minute strike.
Sam Vokes and Johann Berg Gundmundsson put Burnley 2-0 up, only for Palace to hit back through second-half goals by substitute Connor Wickham and Christian Benteke.
But in the fourth minute of stoppage time, Gudmundsson crossed for Barnes to fire home and condemn Palace -- who later hit the post through Andros Townsend -- to a fourth straight defeat.
Stoke City drew 1-1 at West Ham United, with Bojan Krkic exploiting an error by home goalkeeper Adrian to equalise in the 75th minute after a Glenn Whelan own goal had put the hosts ahead.
