They're known for their achievements in the sporting world. But when it comes to social media, who is the best at engaging their fans?
We picked out our top 10 Twitter accounts belonging to some of the sports world's biggest personalities, from football, basketball, tennis, golf, and motor racing.
Who else do you think is worth following on Twitter?
1. RIO FERDINAND (@rioferdy5)
Unlike many footballers on Twitter, Ferdinand maintains a genuine presence. He isn't afraid to speak his mind either, which leads to many retweetable moments.
Players feigning injuries or players that go down & act like they have been hit by a lorry etc do my head in massively. Punish them too??— Rio Ferdinand (@rioferdy5) April 1, 2012
2. MICHAEL OWEN (@themichaelowen)
Open about sharing his personal life, and offers good commentary on the footballing world. Also worth following because of his frequent (and entertaining) public spats with TV presenter and Arsenal fan Piers Morgan.
I don't care who you support, if Ferguson's departing speech didn't leave a lump in your throat I don't know what will. Absolute legend.— michael owen (@themichaelowen) May 12, 2013
3. JEREMY LIN (@JLin7)
Taiwanese-American basketballer Jeremy Lin tweets both jokes and insights into the NBA, and interacts with his fans as well.

7. JASON DUFNER (@JasonDufner)
One of the funnier, driest golfers on Twitter. He loves to tweet about his support for American football team Auburn University.
8. IAN JAMES POULTER (@IanJamesPoulter)
One of the first golfers to develop a Twitter following, the Arsenal fan also shares his witty insights - and sometimes, colourful rants.
On the plane on the way back to Orlando, why does it feel like we just robbed a bank. Not sure how long it's going to take to sink in.— Ian Poulter (@IanJamesPoulter) October 1, 2012
You can't educate pork you just have to salt it.... So many people have no idea what it takes to schedule a season. Can't play every week.— Ian Poulter (@IanJamesPoulter) October 3, 2013
