It was a night to forget for Manchester United as they let a two-goal lead slip and conceded a last-minute equaliser against Carlo Ancelotti's Blues.
The best of both worlds saw United's attack take them into the first half break with a 2-0 advantage, however, it was the defence that ultimately cost them the three points in a huge game for The Reds.
Title race over?
United knew this game would present a great chance to build momentum on their emphatic 9-0 win over Southampton midweek.
A win against Everton, and with Liverpool and Manchester City battling it out on Sunday, United could have been level on points with City, as long as Liverpool did them a huge favour.
However, following United's result, City now have the opportunity to extend their lead at the top of Premier League.
United fans will now be thinking 'what if' they're side had beaten Sheffield United and Everton. Six points gained over those two sides would have put them in the hunt for the title - instead now it's five points dropped.
A worrying defence
Last night, The Toffees scored three goals from three shots on target. It was a smash and grab result, but United continue to struggle to see out games and individual errors is what lost them the game.
Old Trafford this season, United have conceded 30 goals, only Newcastle United (21) and West Brom (31) have shipped in more goals at home. An inexcusable stat.
The Reds' defence have time and time again struggled with defending corners and set pieces this season - conceding from a corner or set piece against the likes of City, Spurs, Sheffield United and Paris Saint Germain.
David De Gea was heavily scrutinized for his part to play in two of Everton's goals.
Firstly, he pushed the ball into Abdoulaye Doucoure's path for him to score, and secondly, he failed to come off his line quicker for Calvert Lewin's equaliser.
United's Number One has been seen to cost his side points in important games, and his poor performance last night, could tempt Solskjaer to start Dean Henderson in place of out of form Spaniard.
