Manchester United manager Jose Mourinho is reportedly unhappy with the FA after it emerged that England staff were with Wayne Rooney when he was pictured at a wedding at the team's hotel while on international duty.
The Sun newspaper published photos on 16 November that appeared to show Rooney drunk at a party in the early hours of 13 November – a day after England's World Cup qualifying win over Scotland.
He was released back to his club before England's friendly against Spain due to a minor knee injury.
Citing sources, Sky Sports claims Mourinho is incensed that Rooney was allowed to party until the early hours while under the responsibility of the FA.
Members of the FA as well as teammate Phil Jagielka are reported to have been in the area of the hotel where Rooney stayed up late.
"Naturally Wayne is sorry that pictures taken with fans have been published today," it said.
"Although it was a day off for the whole squad and staff, he fully recognises that the images are inappropriate for someone in his position.
"Earlier today Wayne spoke privately to both [England interim manager] Gareth Southgate and [FA technical director] Dan Ashworth to unreservedly apologise.
"He would like to further extend that apology to any young fans who have seen these pictures."
The FA said it was reviewing its policy on what players are allowed to do during their free time while on England duty.
"All England personnel have a responsibility to behave appropriately at all times. We will be reviewing our policy around free time whilst on international duty," a spokesman for the governing body was reported as saying.
Rooney is expected to be fit for United's clash with Arsenal at Old Trafford this weekend and is in contention to play as first-choice striker Zlatan Ibrahimovic is suspended for the match.
