Chelsea kicked off their 2020-21 Premier League campaign with a 3-1 win at Brighton on Monday.
Frank Lampard's men got off to an ideal start after 23 minutes. New signing Timo Werner drew a penalty after he was taken down by Brighton goalkeeper Mat Ryan, and Jorginho stepped up to give the Blues the lead.
Chelsea kept their advantage into half-time but Trossard equalised nine minutes after the break to settle the hosts.
However, James struck back moments later with a rocket from well outside the box and Zouma added a third 10 minutes later with a side-footed volley from a James corner that took a wicked deflection before beating a helpless Ryan in goal.
Chelsea next face champions Liverpool in a juicy Premier League encounter on Sunday. While Brighton will host Portsmouth in an EFL Cup second round match on Thursday before visiting Newcastle in the league on Sunday.
