Greece 
Touted as the new Theodoros Zagorakis, but Tziolis has yet to live up to the billing of Greece's legendary former captain.
A physical presence and recognised for his strength, Tziolis is one opposition players will do well to avoid picking an argument with this summer.
However, he is expected to find himself on the substitutes' bench when proceedings begin in June after making only two appearances in qualification.
The 23-year-old Panathinaikos ace will be keen to live up to his promise this summer and is another to watch from Greece's next generation.
Tziolis is also no stranger to a spectacular strike and do not be shocked to see the midfielder wheeling away in celebration after unleashing a long-range net-buster.
