Álvaro Arbeloa.
Because he showed up for the freezing Real Madrid-Mallorca game in a short-sleeved shirt. And no gloves.
Here is the breakdown of how Madrid’s players were dressed for this snowy game, in order of most to least bravery:
Short-sleeved shirt, no gloves: Arbeloa
Long-sleeved shirt, no gloves: Cristiano, Gago, Benzema, Guti, Granero, Garay
Long-sleeved shirt, with gloves: Kaká, Higuaín, Albiol
Short-sleeved shirt with long-sleeved shirt underneath, and gloves: Marcelo, van der Vaart, Xabi
Note: Iker was not rated because he wears gloves no matter what, and never a long-sleeved shirt (have you noticed that he cuts the sleeves and bottoms of all his shirts?) Anyway, he wore a short-sleeved shirt, and a neck protector. And the gloves, of course. Maybe the captain’s armband kept him warm?
