Chelsea were given a helping hand in the race for the top four on Sunday.
Arsenal dropped points away at Everton - their sixth defeat of the season away from the Emirates - to open the door to the Blues and Manchester United behind them.
Just three points separate Tottenham in third and United in sixth, with six games of the Premier League season to play.
Everton deserved their victory over a poor Gunners side at Goodison Park, with Phil Jagielka's goal the difference between the two sides in the end, although the Toffees might have enjoyed a more comfortable afternoon, but for some profligate finishing.

Helping them to secure the three points, by keeping a clean sheet, was defender Kurt Zouma - on loan from Chelsea.
Zouma joined Everton from the Blues on a season-long loan in the summer and has played all but five of the Toffees' 33 Premier League games this season.
Everton have kept three clean sheets in their last four games, tightening their defence under Marco Silva, including the shut out against the Gunners on Sunday, which helped his parent club in the race for the top four.
And the Blues supporters were delighted to see Zouma working his magic on their top four rivals.
