Ferrero is definitely Spanish. If he has an arab father he'd have another name, that's 100% sure.
Michael Schumacher is the only one in the world who hides his arab background from the rest of the world. Probably too embarassed to say he's half algerian.
ok, let-s clarify this, the father of Andre Agassi is from Iran but his ethnicity is "armenian". The armenians lives in many countries besides Armenia, like Turkey, Azerbaijan, Iran, Lebanon, Israel, Palestine, Syria, etc.
and about Ferrero his last name is totally spanish, he was born in Onteniente, Valencia, but his last name comes from Oviedo, Spain
