Manchester Untied chief Ed Woodward was seen debating with Sir Alex Ferguson during the club's 3 - 3 draw with Sheffield Untied on Sunday.
The Red Devils fans were discussing the incident on social media, being furious at Woodward for the way he was talking to Ferguson.
A body language expert Judi James has opened up on the incident.
In the first picture Woodward points his figure during their conversation.
James explained:
“This gesture is like an invitation to a 'duel', with the index fingers acting as weapon-substitutes. In this case Woodward appears to avoid aiming any direct pointing with the back of the hand on top at Ferguson, which would form the kind of mimed 'poking/prodding' gesture that can often prompt an angry response. The one shot where he is pointing directly he keeps his hand palm-upward, suggesting he's keen to win verbal points rather than engage in an angry fight. Woodward's facial expression suggest total emphasis on his message, as though he could be responding to a criticism and keen to defend himself actively. His brows are fully raised, his eyes are wide open and staring in emphasis and his mouth is wide open too. There's a hint of humour in the slightly rounded cheeks here though, rather than suggestions of genuine, open anger. Both men have activated their index fingers here, which is a bit like unsheathing their weapons. Ed's is pointed to one side though and Fergie's is dropped down, so this isn't toe-to-toe at this moment.”
