Liverpool's title challenge suffered a stunning setback as they conceded three goals in the last 14 minutes of an astonishing 4-3 defeat against Bournemouth, while Everton's Leighton Baines scored a last-gasp penalty to earn a 1-1 draw against Manchester United on Sunday.
Jurgen Klopp's Liverpool missed out on a chance to go second in the Premier League and instead remain four points behind leaders Chelsea after their incredible meltdown at Dean Court.
Goals from Sadio Mane and Divock Origi had Liverpool ahead at the break and the points still seemed to be heading back to Anfield when Emre Can's strike restored their two-goal advantage following Callum Wilson's penalty.
But Ryan Fraser, who had come off the bench to win the spot-kick, then buried his maiden Premier League goal before crossing for Steve Cook to superbly equalise, with Nathan Ake bundling home a last-gasp winner as Loris Karius failed to hold another Cook effort.

REUTERSBournemouth are in just their second season in the top-flight and this was arguably the tiny south coast club's finest hour.
At Goodison Park, United took the lead in the 42nd minute when Everton goalkeeper Maarten Stekelenburg made an ill-advised decision to come for Anthony Martial's cross and Zlatan Ibrahimovic lofted his shot into the net for his fourth goal in his last three games.
But Jose Mourinho's side couldn't find a crucial second goal and the United manager was punished for sending on Marouane Fellaini in the closing stages when the former Everton midfielder carelessly conceded an 89th minute penalty with a clumsy challenge on Idrissa Gueye.
Everton left-back Baines stepped up to slot the spot-kick past David de Gea to leave sixth placed United 13 points behind Chelsea after a third successive draw left them with only one win in their last eight league games.

While City spluttered, Arsenal stepped up their title challenge with a ruthless performance that kept them within three points of Chelsea.
