The use of Twitter in football
The use of twitter by professional footballers has divided opinion.
West Ham co-chairman David Gold is a prolific tweeter, while Hammers manager Sam Allardyce has labelled it "dangerous".
Late Kick Off London & South East paid a visit to Upton Park for Saturday's match against Crystal Palace to canvas opinion on the 21st-century footballer's social network of choice.
Late Kick Off is shown on BBC One on a Monday evening (23:05 GMT).
You can also watch the programme again on the BBC iplayer via the Late Kick Off website.
