Conor Gallagher believes Brighton "wanted it more" than Chelsea in the Blues' 4-1 defeat on Saturday afternoon.
Chelsea were poor at the Amex Stadium, where they went 3-0 down to the Seagulls in the first half. Leandro Trossard opened the scoring on five minutes before Ruben Loftus-Cheek and Trevoh Chalobah both scored own goals.
Kai Havertz replied for the visitors early in the second half, but Pascal Gross scored late on for Brighton to restore their three-goal advantage. Gallagher, who played 79 minutes before being replaced by Hakim Ziyech, has now questioned the mentality of the Chelsea squad.
