Manchester United defender Rio Ferdinand has offered to help out a rail passenger with her charity work after a chance meeting on a train following a request on Twitter.

The commuter spotted the United centre-back on her train journey, and Tweeted her friend with the news. Her mate promptly tweeted Rio Ferdinand, asking the Manchester United man to introduce himself, and to ask about her pal's charity work for Dance Aid.

Ferdinand did just that, walking up to the girl on the carriage, and after a quick chat, the former-Leeds and West Ham defender offered to help out her charity with any promotional work.

Tom Adams, Eurosport journalist, first revealed the encounter on Twitter: "Housemate's girlfriend on train today and spotted Rio Ferdinand was in her carriage. She texted her mate, who then tweeted @rioferdy5 to tell him and ask if he could talk to her about her charity.

"Girlfriend has no idea this happened, looks up to see Rio sitting down opposite her, unprompted. He then asks her all about the charity and agrees to do some work for them."

Rio Ferdinand is one of the most followed footballers on the social media site, with more than 3.7m followers.

And the United star took to his own personal Twitter account after the meeting to confirm the news.

He said: "Yep, news travels fast on this Twitter! See if I can help out."

Next up for Ferdinand and United is Liverpool at Old Trafford on Sunday. The Premier League leaders won the last meeting between the sides 2-1 at Anfield.
