It's okay, it's okay don't panic
We don't know, maybe in january we will be "omg i looooooove Nike for that shirt and that short" ! I trust the people of that kind of firm to know how to deal with a so sexy and good-looking guy
NO. HE NEEDS STRIPES.
besides, don't you know that it's not about looks... It's about the... brand. Adidas is cool and Nike is not. That's a fact and we all got so used to it.
And no, i'm not kidding. I'm totally serious and i quite simply can't imagine Marat in Nike (without stripes on those SPECTACULAR 'Baricade IV' shoes and on his shorts).
Edit: ok he CAN look good in Nike too, depending on what he'll choose, but it'll feel weird for some time.
