Manchester United boss Sir Alex Ferguson will escape any action after his gestures to the Reading bench during Saturday's 2-0 win.

An FA insider told The Sun: "It is likely we will write to Sir Alex and ask for an explanation.

"We will probably look at the video of the match as well.

"But these things are often open to interpretation and it is unlikely the United manager will face a disciplinary charge.

"We also understand Reading have not received any official complaints."
