Liverpool has commenced the installation of rail seats in the Kop end as part of a season-long trial at Anfield.
The Reds announced in June that the first stages of the installation of the rail seats had been completed ahead of Jurgen Klopp's side's pre-season games against Athletic Club and Osasuna on Sunday and Monday respectively.
Further work, which will see seats converted to seating with safety rails, is due to be completed in time for Liverpool's first home game of the season, when they face Burnley in the Premier League on August 21.
