Twitter can be an incredible source for news, videos, and immediate reaction to major events in the world, but it can also house some right gobshites.
Many people out there love nothing more than winding up public figures, and it seems that athletes and former sports stars come in for tirades of abuse from keyboard warriors all over the world.
For example, every single tweet that Gary Lineker sends immediately receives dozens of replies that take one word of what he has said and put it beside "Shat on...", reminding the former Barcelona and England striker that he once shat himself on the pitch against Ireland at Italia 90.
Lineker has given up trying to find out why people seem so obsessed with this (honestly, go and look at the replies to Lineker's latest tweet at time of writing), but there are many players out there who seem to love calling a spade a spade, or in this case, a gobshite a gobshite.

If he's not on RTÉ letting the world know what he thinks about the state of English football, Didi is probably live-tweeting cricket on twitter, and if he's not doing that he's interacting with his followers in a way that lets his German-ness shine through with some magnificent blunt responses.
John Arne Riise
There can't be many footballers as active on twitter as former Liverpool full-back John Arne Riise, as he is always replying to fans and... Other people as well.
Of course two of our list members here had a very personal twitter spat a few years back, so be warned, you'd better be ready for a reply if you take a shot.
