Rio Ferdinand has trolled Jamie Carragher with a cheeky four-word dig on social media after the two pundits found themselves embroiled in a high-profile and public spat.
Given their affiliation to Manchester United and Liverpool respectively, Ferdinand and Carragher might never see eye-to-eye on all matters relating to the beautiful game - but their relationship hit a stumbling block over the last few days after Carragher seemingly called Ferdinand a "clown".
Carragher took aim at Ferdinand when AC Milan were awarded an overturned penalty during the Champions League semi-final opener with neighbours Inter Milan. Ferdinand reckoned the spot-kick ought to have stood, but Carragher wholeheartedly disagreed.
