Tottenham midfielder Hossam Ghaly has apologised for his petulant behaviour during Thursday's 1-1 draw with Blackburn Rovers at White Hart Lane.
The Egypt international threw his shirt to the ground after being substituted, but now regrets his actions.
"I am just so angry with myself," he told the club's official website.
"I have always considered it an honour to wear the Tottenham shirt and I never intended to show any disrespect.
"I knew things weren't happening for me out there, my play was terrible and I could hear the crowd jeering me. I was so upset at the fans' reaction.
"I have enjoyed playing in front of the club's supporters all season and I felt I had given of my best all the time and played some decent football.
"It is always hard to accept being substituted after such a short period of time and I was upset and taken aback by the cheering. I am a player who plays with my heart.
"I know my reaction was totally wrong. I have apologised to the manager and I also want to apologise to the fans. I hope they don't judge me on this incident alone. I have tried hard for the club this season."
Spurs boss Martin Jol had said after the game: "We have certain rules and arrangements, whether it is Dimitar Berbatov, Robbie Keane or Jermain Defoe or Hossam Ghaly, it's no different to me, so we will deal with that internally.
"It was out of character because he is a very good boy, he's always disciplined and every time he was involved he did well, but you couldn't say he did well this time."
