I imagine this little bird was flying around the Castelão today, saw a soccer match going on, and thought "Hey, why not stop by and check out Neymar?":
I like his quickness and explosive speed, to be honest. I fear size could be an issue though as he could easily be accidentally stepped on by a defender. Then again, everyone loved to say that Lionel Messi was too small and people are trying to say something similar about Neymar, so who's to say what's possible.
Hopefully some talent scouts were watching and saw the bird's excellent run.
Be safe out there our little avian friend and remember, don't go to Europe until you're good and ready. It's good advice for any player really, but it's especially good advice for a bird as that would be a really long flight I expect. Even if the bird was able to get some favorable wind patterns ... I'm just going to stop.
