The league is open.
Chelsea were successfully nullified, failing to register a single shot on target in a league game for the first time since 2007, and now lead second-place Tottenham Hotspur by just four points.
'We have to react in the right way, ' said Chelsea centre-half Gary Cahill.
"And I repeat the same: They are phenomenal in counter-attack, and when they have the ball it's more hard for them and when they have the ball we are compact and when they try to play counter-attack we were always in control of these link positions".

Young insisted he "was concentrating on Manchester United" when the rumours of a move to China surfaced and has not yet looked beyond the end of his current deal at Old Trafford.
As good a tactical masterclass as it was from Mourinho, there was a touch of fortune about both goals.

Chelsea had wanted a handball against Herrera as he won possession in a midfield challenge before playing the pass, but referee Bobby Madley waved play on.
Pep Guardiola's men kept on attacking thereafter as Sane made the score line 2-0, 13 minutes from time and literally finished the game, before Sergio Aguero scored the third with a close-range header.
Ander set up Marcus Rashford to score the opening goal on seven minutes, doubled the lead with a deflected finish after half-time and even man-marked PFA Player of the Year nominee Eden Hazard out of the match. United's unbeaten run in the league extended to 22 games, the longest in Europe's top five leagues.
Chelsea is still the favorite for the title, with the only obvious stumbling block in its run-in being a trip to Everton on April 30.
"The pressure is normal and we are lucky to have the pressure", Conte said.
