Luighi recently signed a new contract with Palmeiras that will keep him at the club until 2029, with a buyout clause set at £70 million.
Despite this, it's believed that Palmeiras may be willing to sell Luighi for a lower price, given their previous deal with Chelsea for Estevao Willian.
Estevao had a £60 million buyout clause, but Chelsea agreed to a £28 million fee last year.
Arsenal has been following Luighi for the past two years, showing their interest in the young player.
