The great former Roma defender Walter Samuel was a special guest at Trigoria on Wednesday, as he watched the first-team train.
The Argentine, a member of the club's 2000-01 Scudetto-winning side, is widely-regarded as one of the greatest defenders in the club's history.
Due to his no-nonsense approach to defending, he earned the nickname 'The Wall'.
After watching Jose Mourinho and his group at work, Samuel took a tour of the current Trigoria facilities - including a trip to the club's archive, where he was reunited with one of his old shirts.
