Willian has played alongside some truly talented Brazilian forwards over the past few years.
And in Gabriel Martinelli, he sees a youngster with all the potential to make a big impact for club and country.
"He has a great future I think," Willian told Arsenal Digital. "He can be one of the best players in the Premier League, no doubt.
"It's because of his quality and also without the ball you can see that he is always trying to help his team and do the job without the ball. So I think he can be one of the best players.
"I think when he starts to play again, I know he is injured now, but when he starts again, it's about time for him to go to the Brazilian national team."
