Every unbeaten run must come to an end at some point.
Saturday afternoon's 4-1 defeat to Brighton felt like everything that could have gone wrong for Graham Potter did. Chelsea went 3-0 down in the first-half after Leandro Trossard's opener was followed by two own goals from Ruben Loftus-Cheek and Trevoh Chalobah, respectively.
Kai Havertz offered the visitors a glimmer of hope down at the Amex Stadium but his goal was merely a consolation when Pascal Gross restored the Seagulls' three-goal advantage late on. It was a nightmare return to the south coast for Potter, who now has plenty to work on before his side take on Dinamo Zagreb on Wednesday night.
