Baptista is set to hold talks with Arsenal over Denilson’s future.
Denilson returned to Brazil last summer on a year-long loan deal.
Sao Paulo are now keen to extend that loan spell, as they could not afford his transfer fee.
Vice-president Joao Paulo de Jesus Lopes told Globo Esporte: “Arsenal’s staff want him to return but we are waiting for [director of football] Adalberto Baptista to have talks with them.
“Maybe we will manage to extend the loan for six more months or even another year.”
When asked what Arsenal think of Denilson, De Jesus Lopes added: “They liked his performances, they liked Denilson’s development. That’s why they want him to return.”
