He's decent, but he might find it hard to manage those big stars. Portugal squad is not that strong, but they do indeed have some big players.
A side note is that: he has been coaching in Portugal, and Greece (only those 2) and was the head coach of the Greece in the last world cup.
Fernando Santos has been appointed Portugal's new head coach.
So what do you guys think? will he handle big-players like Cristiano, Moutinho, Nani, Pepe, Coentrao, Carvalho to EURO 2016 success?
