Chelsea lost 2-1 to Brighton, as goals from Georginio Rutter and Kaoru Mitoma cancelled out Bart Verbruggen's early own goal. However, questions have been raised over the legality of the Seagulls' winner in the 57th minute, as Tariq Lamptey looked to handle the ball after his shot was blocked and ricocheted off his hand in the build-up to Mitoma's winner. Maresca has now opened up about the match and criticised the lack of a Video Assistant Referee (VAR) system.
Speaking to BBC Sport, Maresca said: " I think the handball [before Brighton's second goal] is quite clear. In the last two or three days there were many different moments in different games. Without VAR it's complicated."
The FA Cup does not have VAR until the start of the fifth round due to a lack of necessary technology at smaller stadiums.
