Pato ended his six-year stay with Italian side AC Milan in January to return to his native country and join Corinthians.

Despite being at the club for less than a year, de Andrade admitted that Pato could leave the club if a substantial offer comes in from either of the north London clubs.

"Given his value, I think it is difficult for him to move to another Brazilian club," he told Radio Bandeirantes.

"If the two clubs [Arsenal and Tottenham] are interested in Pato we do not exclude to sell him during the winter transfer market."

Pato revealed last week that he rejected the chance to join Spurs in the summer, preferring to remain in Brazil with Corinthians.

Gunners manager Arsene Wenger is an admirer of Pato and is keen to bolster his strike force in the January transfer window with Nicklas Bendtner and Yaya Sanogo the only real back-up to the prolific Olivier Giroud.

Andre Villas-Boas is eager to secure a deal to bring Pato to White Hart Lane and will battle Wenger for his signature.
