Chelsea slump goes on as Brighton earn draw
Chelsea surrendered a lead against Brighton for the second time in a month as both sides had to again settle for a 1-1 draw on Tuesday.
The European champions went ahead against the run of play when Hakim Ziyech's snap shot caught Robert Sanchez in the Brighton goal by surprise.
But the Blues have now just one of their last seven league games as Adam Webster's towering header earned Brighton a fully deserved point.
Thomas Tuchel was critical of his forward players after a 1-0 defeat at Manchester City on Saturday, but kept faith with Romelu Lukaku and Ziyech in attack as Timo Werner and Kai Havertz were again left on the bench.
There was little to impress the German once more as Chelsea's slump leaves them looking over their shoulders at the contenders for a top-four finish rather than a title challenge.
They remain third in the table, 12 points behind leaders Manchester City having played a game more.
Lukaku had Chelsea's one clear chance to retake the lead when Sanchez made amends for his earlier error by blocking the ball into the side-netting.
Chelsea's record signing was then replaced as Tuchel turned to his compatriots Havertz and Werner for the final quarter.
The German international duo were just as ineffective as Brighton held out comfortably and could even have snatched all three points with more composure on the counter-attack.
Chelsea host Tottenham on Sunday in their final league game for nearly a month due to an international break and their commitments at the Club World Cup in February.
Should Tuchel's men fail to turn things around at Stamford Bridge, they could return from Abu Dhabi with their place in the top four under severe threat as the chasing pack make up their games in hand.
