Wayne Rooney has reportedly threatened to reduce his off-field role with England in protest at his three-match ban from the Football Association.
The 20-year-old England striker was banned for his red card in a pre-season friendly against Porto on 4 August.
Reports on Sunday claim Rooney's agent Paul Stretford has sent a letter to FA chief executive Brian Barwick, saying his client "feels extremely let down".
Rooney is apparently ready to pull out of commercial activities for the FA.
Stretford's letter reportedly said: "I am writing on behalf of my client to express his utter dismay at the decision not to overturn the ban.
"Decisions like this one with Wayne Rooney obviously makes my job very, very difficult"
"Rooney feels extremely let down by the FA on this matter.
"While he will continue, if selected, to play for his country with pride and commitment, he is considering withdrawing his support for the FA's commercial programme.
"In other words, he will not allow his image to be used or exploited, or participate in personal appearances for and on behalf of the FA's commercial partners unless he is satisfied with how the FA conducts its affairs in regard to player matters."
His ban starts on 23 August and he will miss the fixtures against Charlton, Watford and Tottenham.
England manager Steve McClaren has admitted he was unhappy with the FA's decision to give Rooney a three-match ban.
"The decision has not made my job any easier in building relationships with the clubs," said McClaren.
"I am not criticising anybody about making a decision but when I have to build a relationship with the clubs and the managers and decisions are made like this one with Wayne Rooney then that obviously makes my job very, very difficult."
