A lot of players that end up becoming legitimate Super stars had to carry around the tag of "big game chokers" until later in their career, when their quality couldn't be denied.
They used to say this about Kaka at Sao Paolo, Henry at Juve and Arsenal, iBra for most of his career (I still do
), even CR7 and Messi early on. The reverse can happen as well....a young player can be unstoppable against anyone (Pato, Adriano) and then fizzle out completely.
Obviously, they are going to make their name and numbers against the fodder at first, and as they grow they will become better against the tougher opposition. I'm very hopeful for this kid.
