Arsenal boss Arsene Wenger has hit out at Manchester City's new owners.
"The more money there is in the game, the more important it becomes to respect the rules," Wenger said. "More money means that people are very demanding with other people. They think they have the right to do things as they see fit. In sport, until now, the rules were quite well respected. I cannot say that every transfer was respected to the letter of the law, but usually there was a respect among clubs and the statements you made.
"The beauty of sport is to respect the rules and to win. People who do not should not be allowed to win."
Part of Wenger's concerns come from the additional competition City offer for a Champions League place, which the Frenchman recognises is "in jeopardy" while arguing that his youth-centred squad remains capable of lifting a major title.
"They sell the story to our fans that because we don't buy players for £135m, we cannot win," he said. "We have to be strong and say that yes, we can win."
