Brighton v Chelsea Live: Graham Potter's Blues go chasing a top four place as he faces former club Brighton for the first time

Graham Potter's unbeaten start at Chelsea comes to an end in spectacular fashion as Roberto de Zerbi gets his first win.

The Brighton fans are in heaven.

The home side seal victory with their fourth goal in stoppage time.

Julio Enciso smashes two shots at Mendy that he can only parry before Pascal Gross finally puts it away.

It would almost take a miracle for Chelsea now.

The Chelsea right-back is overwhelmed by two Brighton defenders and gives away possession in a dangerous area but the referee comes to his rescue with a debateable foul.

Time is ticking away and the home side must now be feeling confident of holding on for a famous victory.

An ovation greets the Belgian as he is replaced for the final minutes.

Loftus-Cheek cuts it back from the right and the German is in plenty of space, but he is leaning back and lifts his shot well over the bar.

Sanchez came and missed but there was no Chelsea player there to put it away.

The England midfielder has switched to right-back in this second half and is doing well down the flank.

The Belgian looked to have fairly won possession, but it's given as a foul.

Pulisic and Gallagher are off for Ziyech and Broja.

Estupinan sends in a dangerous cross and Webster wins the header, but the chance needed someone else to put it away.

The Brighton teenager knocks the ball beyond Chalobah near midfield and races in behind. With Trossard in space on his right, Enciso decides to try to shoot through Thiago Silva and the chance goes begging.

The Brighton forward had support but uncorked a powerful shot from distance. Mendy was comfortable making the save, though.

The full-back's first touch is an underhit pass which Aubameyang snaps up. Chelsea can't make the chance count, but Brighton need to be careful.

The former Chelsea man is on in place of the impressive Japan winger.

The Gabonese striker was winding up to shoot but Brighton's defence surged to rob him of possession.

The Chelsea full-back might have been caught in two minds there as he puts his shot well off target.

The ex-Barcelona striker tries a shot from the left and Sanchez can only push it out for a corner.
