Manchester United players were involved in a post-match fracas with Chelsea ground staff after Saturday's 2-1 defeat at Stamford Bridge.
Patrice Evra, Gary Neville, Park Ji-Sung and Paul Scholes were warming down after the fixture when a row ensued with the ground staff tending to the pitch.
A Chelsea spokesman told reporters: "We will be studying the CCTV footage of the incident and take whatever action is appropriate."
After the game, United defender Rio Ferdinand told reporters he had apologised to a steward after accidentally kicking her following Michael Ballack's late penalty winner.
Ferdinand kicked out at a brick wall as he walked off the pitch but also made contact with the female steward.
"Unfortunately, a lady was standing by and I accidentally brushed her with my foot. I apologised profusely and went back to make sure she was okay," he said.
"I have arranged for a bouquet of flowers to be sent to her.
"Credit to her, she laughed it off and was very understanding. She said she wasn't hurt."
