The article 17 allows players to buy out their contract after three years if they are less than 28 years and two for the others.

"The situation at the moment has become much more unstable with the Webster clause (Article 17). Every new rule provokes a little bit more inflation and instability because the players can always move out earlier and quicker, "the Frenchman told the Guardian.

"For a club like ours, which is going for a youth-team policy, this rule is very detrimental. We educate them and then they could leave at some stage when they get mature.

"This rule is not good and we live in a world where it is also an incitement to inflation because you always have to look at their contracts. Stability inside the club is a big problem because that problem is a huge inflation factor," added Wenger.

Egyptian keeper Essam Al-Hadari invoked the 'Webster clause' to force a move away from Ahli and joined Swiss side FC Sion. The FIFA Dispute Resolution Chamber hasn't given a verdict in the contractual dispute but authorized the Swiss Federation to provisionally register him.

"I'm not convinced that rule will resist for a long time. One day, a 26-year-old will go to court and say it's age discrimination. Why can you move out at 28 and not 26 after two years?" concluded Wenger.

The Gunners boss is facing the prospect of losing Alexander Hleb who has reportedly met Milan bosses last week.
