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

Chelsea have begun the second period with plenty of energy.

The visitors are changing to match the home side's back four.

Can Chelsea turn things around in the second period?

Edouard Mendy will be in the Chelsea goal for the second half after Kepa apparently suffered a first-half injury.

The home side have blown their visitors away in the opening 45 minutes.

A sensational performance from Brighton has them 3-0 up at the break and Chelsea are lucky it isn't more.

Brighton could easily be five up here. Chelsea have no answer to their energy and organisation.

Cucurella turns over possession on the edge of his own box and Trossard very nearly finds the space to score again.

Brighton could not have played much better than this and they are well worth their lead.

Chelsea are 3-0 down as Brighton cut them apart again.

Estupinan races into space down the left and rolls his cross towards Mitoma. It looks like Chalobah got the final touch.

The England forward is Chelsea's only option in attack but he just keeps losing the ball.

Relentless waves of attack from the home side who are completely dominating this match.

Trossard is caught flat-footed as the corner is flicked right to him. That could so easily have been Brighton's third.

Chelsea's keeper dives to claim a tricky Brighton cross but carries it out over the line for a corner.

The home side play right through Chelsea's midfield with intricate passes before spinning it out wide into space.

Chelsea can't deal with this.

The Chelsea winger is surrounded and just sort of falls down. He seems to want a penalty but good luck explaining what it would have been for.

The visitors are finally pushing Brighton back with a bit of sustained possession. Can they make it count?

Sterling finds Mount at the top of the box, but the Englishman's pass for Havertz has too much on it and the German can only race out of play with it.

Brighton get into the Chelsea box again but can't get a clean shot away. Eventually Caicedo does shoot, but fires inches wide.

Brighton have identified the space in this game and they're playing into it at every opportunity. The Chelsea backline are so far away from their goalkeeper.

The Spanish left-back can't find an option for a throw-in so the home fans get plenty of time to communicate their feelings.
