Arsenal temporarily moved ten points clear at the top of the Premier League table after a dramatic 2-0 win against Everton on Saturday.
Two late strikes from substitutes Viktor Gyokeres and youngster Max Dowman secured the important win.
The Gunners looked to be on course for a frustrating goalless draw at the Emirates Stadium until Gyokeres broke the deadlock in the 90th minute.
The Swede tapped the ball into an empty net off an assist from another substitute Piero Hincapie off a dangerous cross from Dowman.
Then in the 96th minute youngster Dowman sealed the win as he raced towards goal and rolled the ball into an unguarded post after Arsenal cleared a corner.
At Stamford Bridge Chelsea suffered another defeat as they went down 1-0 to Newcastle.
