Arsenal manager Arsene Wenger believes a review into current tapping-up laws is necessary as he attempts to hold onto Cesc Fabregas and Samir Nasri.

Clubs are prohibited from approaching under-contract players directly and, while Wenger stopped short of accusing any team of such action, he believes they are able to find ways around the rule in order to help lure their recruitment targets.

Asked if any clubs had tapped up his players, he said: "I would like to return the question to you. What do you think?

"We live in a realistic world. I do not want to assess what I cannot prove, but I know how things happen."

He added in the English press: "It doesn't necessarily go through the player or the agent, but I think it is a rule that has to be reviewed. It's not really respected.''

Wenger has been critical of the manner in which his players' futures have been played out in public this summer, hitting out at Manchester City boss Roberto Mancini and Barcelona midfielder Xavi.

Wenger's comments come as Manchester United fullback Patrice Evra has admitted to trying to tempt Nasri to join him at Old Trafford.

"Of course I would like to see Samir at United," Evra said. "I've talked a lot with him during the holiday and told him how great it is to play for Manchester United and how important it would be for him to become one of the biggest players in the world.

"He said that it's a privilege that a club like Man United want him, but that he has to think about his future and talk with his agent. I'm not Nasri, I'm not his agent or his dad, but I would definitely tell him to come to Man United. Definitely.

"I remember I made that little joke saying that he's a prince now, but if he wants to be the king then he has to join Man United. But that's the reality and I've told him that. I said: 'If you want to win trophies you have to come here.' In five years I've won 12 trophies, and I don't know if I'd have won more with another club."
