"I am writing to make an official complaint with regards to Mark Halsey's actions during the match between Leeds United and Nottingham Forest on Saturday 2nd April 2011.
1) Mark Halsey can clearly be seen hugging and shaking hands with many Leeds players before kick off. He was seen hugging and patting one player on the back and whispering into his ear.
2) The hand ball by a Leeds player in their own box early in the first hals was missed even though Mark Halsey was right in line of it.
3) Leeds manager Simon Grayson ran on to the pitch when a tackle was made and his player ended up on the floor. No action was given even though managers are not allowed onto the field of play.
4) Chris Cohen blatantly did not intend to injure the player he went into a tackle with and subsequently got sent off for. The Leeds player also had both feet off the ground. Chris Cohen struck the ball first and not the Leeds player.
5) Leeds player Max Gradel ran behind the advertising boards and into the crowd after the fourth goal was scored. No action was taken against him even though other players get yellow cards for doing this normally. There are many examples of this which I'm sure you are aware of but if you need specific examples then please ask!
Please respond with your intended actions towards Mark Halsey and Simon Grayson, If anything at all."
