The Gunners have been tracking the Real Madrid striker for several weeks, and his agent says a deal with the English club now looks close.
Juventus had been in the race to sign the Argentine but now appears close to signing Carlos Tevez rather than Higuain, leaving the door open for Arsenal to scoop up the Real Madrid striker.
"I think that Higuain is now closer to Arsenal," Nicolas Higuain told TuttoMercatoWeb.
"Juventus are a great club, but Gonzalo is too expensive for them."
Napoli was also thought be considering Higuain as a replacement for Edinson Cavani should the Uruguayan complete his anticipated move to Real Madrid, but the player's brother admits Arsenal is leading the chase.
"Napoli are a strong side and that place represents a lot for Argentines," he continued. "Saying that, I can’t deny that Gonzalo is now close to Arsenal."
