Totally agree, living in the UK i can only really follow the Premiership/Championship/La Liga and sometimes the Serie A and Bundesliga on ESPN(which i rarely watch). Other than Youtube i don't think people can judge a player and i can even look good on Youtube with some nice video editing but at the end of the day if Chelsea made an official bid for Neymar then Carlo must see something good in him. It's the same with Dzagoev, everyone used to say he's the new Lampard. Unless your extremely dedicated to watching Russian football i don't see how you can judge the player and just because he loves Lampard and Chelsea doesn't mean he's an instant signing.
We missed out on Pato though, i just think Pato was the exception when it comes to Brazilian footballers over the last couple of years because he has the right attitude and dedication but i guess nobody knows with Neymar. Just because he reminds us of Robinho doesn't mean he has the same attitude as him.
