Rui Fonte's brother says the Portuguese starlet has the talent to succeed in England after making a promising start to his Arsenal career.
The 16-year-old joined The Gunners on a three-year deal at the start of August after impressing on trial from Sporting to become the latest in a long line of young talents recruited from the continent by Arsene Wenger.
Fonte has already found the scoresheet for Steve Bould's academy side and, like fellow young summer recruits Fran Merida, Vincent van den Berg and Joe O'Ceaurill, has also made an impact on the reserve side at Emirates Stadium.
The striker made his debut for the second string in the 2-1 win over West Ham on Tuesday, and following his cameo role has been invited to train with Wenger's first team squad.
Jose Fonte, currently playing for Estrela Amadora on loan from Portuguese giants Benfica, now says his younger brother has the talent and work ethic to make a name for himself in The Premiership.
"He is a great talent," Jose Fonte told Correio da Manha.
"But he knows that he has to work to arrive at the top.
"With my father we try to advise him in the best possible way and are very satisfied for what he can achieve in England."
Fonte is the first Portuguese talent to be taken under Wenger's wing since his early acquisition of Luis Boa Morte, and his brother says the chance to train with players such as Thierry Henry gave his younger sibling hope of making a future impression on his new boss.
"The coach still did not have a talk with Rui, but during the training it is always to stimulate him and to boost his morale," Jose Fonte added.
The 16-year-old will be hoping he gets the chance to make his first team bow in the Carling Cup against West Brom on October 24, as Wenger is notoriously committed to blooding his young charges in England's secondary cup competition.
