Everton, inspired by two-goal Dominic Calvert-Lewin, ended their three-match losing streak in the Premier League with a 3-2 win at Fulham, aided in part by another embarrassing missed penalty by the Cottagers.
Arsenal then had to cope with the sending-off of Nicolas Pepe for a headbutt before eking out a 0-0 draw at Leeds on Sunday, while West Ham moved into the top half of the table thanks to a 1-0 win at bottom side Sheffield United.
At a downcast Craven Cottage, two weeks after Ademola Lookman had failed with a desperately poor scuffed injury-time 'Panenka' penalty against West Ham, Ivan Cavaleiro took over spot-kick duties for Fulham but slipped as he attempted his shot, kicked the ball against his standing foot and saw it loop over the crossbar.
Everton were leading 3-1 at the time and, although Fulham set up a tense finale with a second goal in the 70th minute by Ruben Loftus-Cheek, the visitors held on to return to winning ways after losses to Southampton, Newcastle and Manchester United.
Calvert-Lewin has now scored 10 goals this season - the most in the league - after striking 42 seconds in and again in the 29th minute following an equaliser by Bobby De Cordova-Reid.
Abdoulaye Doucoure headed in a cross from Lucas Digne for his first goal for Everton to put the team 3-1 ahead in the 35th.
Everton started the season with four straight wins but hadn't won any of their previous four games.
"The most important part of the game was to be back to winning," Everton manager Carlo Ancelotti said.
"We lost energy in the second half, the players were tired, I changed to put more fresh legs on the pitch but we lost a bit of quality and we had to defend as a result but in the end it went well."
At Elland Road, Arsenal's Ivory Coast international Pepe was shown a straight red card in the 51st minute after an off-the-ball incident in which he walked up to Ezgjan Alioski and moved his head toward the forehead of the Leeds left back, who fell to the ground theatrically.
Leeds dominated the rest of the second half but couldn't find a way past Arsenal goalkeeper Bernd Leno.
West Ham are eighth after Sebastien Haller fired a superb strike for the only goal of the game, in the 56th minute to secure victory over the Blades.
Chris Wilder's side remain bottom with just one point from nine matches, having scored just four goals.
