The Football Association will ask to see 'all details and TV footage' of the post-match bust-up between Manchester United players and Chelsea staff.
United substitutes became embroiled in a scuffle with Stamford Bridge groundstaff and stewards in the warm-down following Saturday's 2-1 defeat.
FA spokesman Andrin Cooper revealed the governing body will be looking into the matter, saying: 'This will have nothing to do with the referee's report. He would have been in his dressing room a long way from the incident.
'But we will obviously be asking Chelsea to let us see their CCTV footage of the incident.'
Chelsea issued a statement after the game saying they would be 'reviewing the relevant footage and will be considering the appropriate course of action'.
United have also asked to see the pictures so they can consider what action to take.
Patrice Evra, Paul Scholes, John O'Shea, Gerard Pique and Gary Neville were taking part in the warm-down on the pitch when they were asked to move by Chelsea groundstaff.
The row erupted when the players refused to come off the pitch and an altercation broke out between stewards, groundstaff and the United players.
