Arsenal and Barcelona target Cristian Pavon will see his release clause at Boca Juniors increased through a new contract.
The Mirror reports that potential suitors will now have to pay a fee of £37.5 million to land the player.
Both Arsenal and Barcelona have been keeping tabs on the player for some time.
Boca are said to be desperate to keep the player and hope the new deal will ward off any interest in him this summer.
The Argentinian international has impressed for Boca and earned a place in his country’s World Cup squad this summer.
Lionel Messi is reportedly keen for Barcelona to bring the player to the Nou Camp this summer.
The Argentinian superstar has gone as far as telling the Catalan side to sanction a deal for the player, according to reports in Spain.
Arsenal are still thought to be in the market for attackers this summer and Pavon has long been touted as a long-term replacement Alexis Sanchez, who left for Manchester United in January.
