Rio Ferdinand apologised to a female steward at Chelsea after accidentally kicking her when he was en route to United's dressing room.
The defender was venting his anger at the Reds' defeat when the incident occurred.
Rio told ManUtd.com: "I kicked the wall in frustration at the result, just as I have done in the past. Unfortunately a lady was stood there and I accidentally brushed her with my foot.
"I went back to make sure she was okay and apologised profusely. To her credit, she laughed it off and was very understanding. She said she wasn't hurt.
"I have arranged for a bouquet of flowers to be sent to her."
