Manchester United manager Jose Mourinho is facing Football Association action after being asked to explain comments he made ahead of last weekend's Manchester derby.
The Portuguese appeared to accuse rivals Manchester City of gamesmanship prior to the clash at Old Trafford, which the Citizens won 2-1 to move further clear at the top.
Speaking two days before the match, the 54-year-old told reporters: "They have lots of good things. If you ask me one thing that I don't like a lot, it's that they lose balance very easily. A little bit of wind and they fall."
Mourinho, who is likely to face a fine if punished by the FA, has been given until 6pm next Monday to respond to the governing body's request.
Meanwhile, United and City have until Friday evening to provide their observations to the FA following reports of a scuffle after Sunday's game, which reportedly involved up to 20 playing and staff members from both sides.
