From what we've seen so far, Rio Ferdinand has managed to keep a lid on his emotions in his role as a pundit.
This, however, doesn't appear to have been the case during Manchester United's 3-1 victory over Arsenal a few weeks ago.
Rio was again in the BT Sport studio at The Emirates to offer his thoughts on the game. While he did so in a considered, professional manner during the half-time and full-time analysis, he couldn't hide his loyalty to his former club when the game was in play.
Footage recorded in the studio during the game shows the former United defender reacting to a number of key moments in the game, beginning with Jesse Lingard hitting the post and ending with the same player scoring United's third goal of the game.

The clip has alread been widely circulated (largely by United fans), with David De Gea also giving it his seal of approval.
De Gea made a string of saves to deny Arsenal an equaliser when United were 2-1 up and was also described as the best 'keeper in the world by Ferdinand in the video above.

Weeks on from their win in North London, United remain in second place in the Premier League having lost to Manchester City in the derby.
