Arsène Wenger believes that 'sin bins' could be effective in football.
Sports such as rugby and ice hockey already operate a system in which players who commit a yellow-card offence spend 10 minutes on the sidelines before returning to the action.
Wenger is wary of interrupting the flow of a football match but he believes the idea of penalising players immediately has some merit.
"Overall, sin bins could work," he said.
"You have to be a bit cautious about the interruption of the game but the advantage would be that it would punish the team on the day.
"Sometimes you think when a guy gets a second yellow card and is suspended for the next game, that can even be a disadvantage for you because the next game can be against a team who fights with you for a position.
"It is the immediate punishment that is very interesting in that case, and that the team is punished on the day. I think giving an advantage back to the team who have been disadvantaged is a good thing."Copyright 2013 The Arsenal Football Club plc.
