West Ham United defender Matthew Upson is set to change shirt numbers.
The Telegraph says Upson originally wore the famous number six shirt, previously in the ownership of the great Bobby Moore, but the club decided to retire that shirt a year ago in honour of the club's most celebrated player.
Upson switched to 15, but is expected to wear shirt number five for the coming campaign.
Last season, Walter Lopez wore number five, but given his departure and that of several others, changes are expected.
