Luis Suarez will consider submitting a formal transfer request and the possibility of court action if his Liverpool dispute is not resolved, say sources close to the player.
.
The 26-year-old believes Arsenal's bid of just over £40m triggered a clause in his contract that allows him to leave.
.
Liverpool rejected the offer and insist the clause does not force them to sell.
.
"We want to [sign Suarez] if it is feasible in an amicable way," said Gunners manager Arsene Wenger.
.
"We will respect what Liverpool want to do. I don't want to speak about Suarez, because that is between Liverpool and Arsenal.
.
"I am a great believer you have to keep as much confidentiality as possible, which is quite difficult in the modern world.
.
"But we work very hard, not only on the case you name, but on other different cases. We can still strengthen the squad, there is one month to go. We are at the beginning of August and working very hard to strengthen our squad.
.
"I am confident. You look at many teams around us.
.
Nothing has happened until now. At the moment the market hasn't moved a lot. Apart from Manchester City, nobody has done anything."
.
Arsenal made their club-record offer of £40m plus £1 for Suarez in the belief that it would enable them to secure the Uruguay international's services.
.
Liverpool continue to insist that Suarez is not for sale.
.
It is understood that when Suarez signed a new contract in August 2012, he requested a clause that allowed him to depart if Liverpool failed to qualify for the Champions League and received a bid in excess of £40m.
.
Liverpool refused this but suggested an arrangement that obliged them to act in good faith if those conditions were met, which Suarez argues he only accepted because he felt there was verbal agreement from all parties that - despite the new wording - it would work in the same way as a release clause.
Luis Suarez is a kind of player that always stands by what he believes in. I feel his heart is with Arsenal Football Club already. He wants to play Champions League football.
