Chelsea will become the first Premier League club to trial safe standing, starting with their home game against Liverpool on January 2.
The west London club confirmed the news on Tuesday morning, announcing that their new rail-seating will be in full operation in their first game of 2022.
Manchester United, Manchester City, Tottenham, Chelsea and Cardiff are all taking part in the pilot scheme, with the Blues being the first to begin.
WHAT ARE RAIL SEATS?
Rail seats are essentially seats with built-in safety barriers to allow safe standing.
