Liverpool are confident they have no obligation to accept Arsenal's £40 million offer for Luis Suarez.

A source close to the club's American owners explained on Tuesday that lawyers have examined Suarez's contract in detail, and have concluded there is no requirement to sell in the event of a bid topping £40m, merely a commitment to inform the player of any such approach.

"We are 100 per cent confident - there is absolutely no obligation to sell and that is very clear," the source explained to the Mirror.

"We've all examined the clause in detail. All it obliges is good faith negotiations about Luis's future."
