World Cup winner Marcos Cafu is backing the Brazilian signings at Arsenal.
Cafu is keen to see how his fellow countrymen Gabriel and Willian perform at new club Arsenal.
And he believes the two recent recruits share lofty ambitions with the North London side.
Cafu, speaking to Laureus.com, said: “Two great players, I am a fan of both Gabriel and Willian.
“Willian already stood out in the Brazilian team, in the games he played, and stood out at Chelsea.
“Gabriel stood out and continues to impress. I think they are two players who really will perform very well at Arsenal.
“They are players who came, not only to add value, they came to win the Premier League."
