I seriously doubt the "Fernando Alonso Official" on Facebook is a legit account.
On 19th of August "Fernando Official", "Casey Stoner Official" and "Jorge Lorenzo Official" all had this status "Blessed Feast of Ramadan, the Islamic world is all".
1, None of them are Muslim, and I've never seen a non-Muslim athlete talk about Ramadan all my life, sorry.
2, Jorge already has an official account named "Jorge Lorenzo"
3, This Alonso Official page on FB links to several other so-called official account of Robert Kubica and Lewis Hamilton, neither have talked about having official Facebook pages.
4, Given that Alonso and Hamilton have close to a million followers on Twitter and how many fans Messi, Ronaldo and LeBron have on Facebook... do you seriously believe that an official Alonso page on Facebook would have 45 000 fans or what it is?
5, The pictures are probably just hijacked from a Ferrari page or something.
Why don´t you check Alonso´s official website if you are unsure ?
