Many Chelsea fans on social media could not recognise one of their former players, as the Blues' legends trained ahead of their game against Liverpool Legends on Saturday.
The fixtures commemorates Chelsea's 2004-05 season, which saw them claim their first-ever Premier League and first top-flight title in 50 years, as well as the EFL Cup having beaten Liverpool in the final.
The two teams also faced off in the Champions League semi-final that season, with the Reds claiming victory over two legs.
Some notable names on either side include Gianfranco Zola, Claude Makelele, William Gallas, Steven Gerrard, Peter Crouch and Dirk Kuyt.
