The first rail seats at Anfield's Kop end have been installed as part of the season-long trial of seats with safety rails.
Following the initial announcement notifying supporters on June 15, the preparatory work has been completed and the seats are now being installed.
The Kop end will be ready for the pre-season games against Athletic Club and CA Osasuna on Sunday and Monday. The remainder of the work is due to be ready for the start of the new season, with Liverpool's first home game against Burnley on August 21.
As Anfield prepares to welcome fans back for the start of the new season, this trial of seats with safety rails will be in two areas of the stadium that were highlighted in a safety review by the Sports Grounds Safety Authority (SGSA) to have an issue with persistent standing.
