Brian O'Driscoll may not have been the biggest man ever to set foot on a rugby field.
But the ex-Ireland international was superb in still being able to take down the biggest of men with perfectly timed tackles and interceptions.
And he's brought that keen eye for cutting a man down to size to Twitter, after nailing Australian rugby player Adam Ashley-Cooper overnight
The Aussie took umbrage (ooh, fancy) at the ex-Leinster man apparently having a dig at him over moving to France to earns tonnes of cash in the Top 14 with less than glamorous Bordeaux.

It didn't take long for O'Driscoll to hit back

O'Driscoll wasn't going to take that lying down and hit back with a zinger of his own.

Cooper knew he was a beaten man and slunk back to his pile of cash in the south of France
