Thierry Henry would like football to copy the example set by rugby and have a culture of communication between players and referees.
The issue arose in the final stages of Arsenal's game at CSKA Moscow on Tuesday night when the French striker had a goal ruled out for handball. It is an understatement to say that Henry was unhappy with the decision. He tried to talk to the officials at the final whistle but was unable to make his point.
"People talk about footballers behaving like rugby players and accepting decisions," said Henry. "But rugby players can talk with the referee. We can't.
"When you come at them, try to speak to them then they don't give an answer and won't even speak to you. That is difficult to take.
"You don't want to have a go at them, but just to ask them what they saw at crucial times and yet you're not allowed to do that in football.
"I would like the game to be a bit like rugby at times because in football you just cannot speak to referees."
