Manchester City came from behind to draw 1-1 at home to Everton, but will feel like they should have won after missing two penalties.
City could have opened the scoring shortly before half-time when they were given a penalty after Phil Jagielka had tripped David Silva, but Maarten Stekelenburg was on hand to turn away Kevin De Bruyne’s spot kick.
City were made to pay for that miss in the second half when Romelu Lukaku ran from the halfway line before finishing calmly past Claudio Bravo.
The hosts had a chance to equalise when they were awarded their second spot kick of the day after Sergio Aguero had been brought down by Jagielka, only for Aguero to also see his effort turned away by Stekelenburg.
But City did finally find the back of the net in the 72nd minute when substitute Nolito beat the Everton keeper with a header as his side ultimately endured a third consecutive game without victory.

Hazard made it two in the 33rd minute, taking advantage of some sloppy Leicester defending before rounding Schmeichel and slotting into an empty net.
Moses rounded off the scoring in the 80th minute, firing past Schmeichel and into the back of the net after being fed in by a brilliant Nathaniel Chalobah pass.

But West Ham’s 1-0 win at Crystal Palace in the late game put Stoke back down to 18th in the table.
Manuel Lanzini neatly flicked home the only goal of the game after 19 minutes to give the Hammers a first league success in six outings.
Christian Benteke should have equalised from the penalty spot in the last minute of the first half but nonchalantly steered his spot-kick wide.
Palace could not capitalise on Aaron Cresswell’s 75th-minute dismissal – his two yellow cards coming within 51 seconds – although they needed a superb save from Adrian in stoppage time to keep out a Connor Wickham effort and preserve the three points.

Stanislas then got on the score sheet himself just minutes later, slotting into the roof of the net from the penalty spot, before finding the back of the net once more in the second half, with Callum Wilson and Dan Gosling adding a fifth and sixth late on.
