The attacker, who is just 17 years old, has yet to break into Ernesto Valverde's first team, but he has still caught the eye of clubs throughout Europe with one goal in three appearances for Barcelona B.
Ruiz is under contract until the summer of 2019, but it has been suggested that Barca could face a battle to keep hold of him as there is a £3 million buy-out clause inserted in the deal.
Barcelona could get him tied down to a new contract without such a clause, but will have to move quickly as the vultures are hovering over the Nou Camp waiting to swoop.
Reports claim that both Arsenal and Chelsea have been in contact with the player's representatives with a view to hammering out a potential move.
The likes of Cesc Fabregas and Hector Bellerin have left Barca in search of first-team football at a young age in the past, and there is a chance that Ruiz may consider doing the same.
