Rio Ferdinand has made a pretty seamless transition from player to pundit in recent years but, despite covering all the big teams in England, it is pretty clear that his allegiance still lies with Manchester United.
And the former Red Devils captain has once again shown just why he is still considered an icon at Old Trafford with a post on social media today directed at Arsenal legend Patrick Vieira.
#Throwback images on Twitter are usually reserved for Thursday, but Ferdinand has got in there two days early to post a photo - and caption - that is sure to bring back very happy memories for United fans. Gooners, meanwhile, will be hitting the unfollow button.

First, Ferdinand's Tuesday morning post:
Those with a good memory will immediately recognise the photo as an image from the now infamous 'Battle of the Buffet' clash between Arsenal and Manchester United back in October 2004.

Battle of the Buffet
United brought to an end the Gunners' incredible 49-game unbeaten run courtesy of a 2-0 win that day, and rumours ever since have claimed that Cesc Fabregas threw pizza at Sir Alex Ferguson in the tunnel afterwards.
It was certainly a game to forget for Arsenal. For Ferdinand and United, however, it is one that continues to live long in the memory.
It isn't clear if the former England centre-back was intentionally trolling Vieira by using a photo of that particular game but, given Ferdinand's notorious sense of humour, you wouldn't put it past him.
Back in '04 there were no bigger games in the Premier League than those between Arsenal and United and tension was at an all-time high in the one depicted above.
Indeed, Ferdinand himself was fairly fortunate to avoid being sent off in the early stages after a challenge on Freddie Ljungberg.

Ultimately, though, it was Arsenal who were punished by the referee as Ruud Van Nistelrooy converted a 73rd minute penalty before Wayne Rooney put the game out of reach with a goal in injury time.
With Vieira currently the manager of New York City FC in MLS, Ferdinand might have to wait a few hours to hear exactly what the ex-Arsenal captain has to say about his tweet due to the time difference between the UK and the USA.
However, given how outspoken the Frenchman was during his time in north London, it would be very surprising if he didn't respond in some way, shape or form later today.
