"My thoughts are that it is good to have money in football, but it's how you use it. Basically you still have to respect the rules," Wenger said.
"The football bodies have to be very cautious about that.
"You can't have a situation where people just come in and say they want to buy [Cristiano] Ronaldo or they want to buy [Fernando] Torres. That is disrespectful. These players are under contract.
"If a player is under contract then you cannot make public comments which destabilise the club.
"What you have to do is first of all ring the player's club, to ask if they are ready to sell for this price.
"If that doesn't happen, then you have to shut up.
"I believe that the governing bodies can enforce that because this is happening in public."
