Would like to say Lewandowski, but it all depends on how far Poland get. If all teams played the same amount of games or it was just top scorer in the group stages, I'd say Lewandowski. But, it's not so I'm going to for Fernando Torres. Probably sounds bias, but I do think he could get quite a few goals at the Euros.
Funny that both Italian players in the poll will probably not be in the starting 11. RVP can not score at all (only in Premier where the CDs still track the forwards in a man marking and chase them to the touch line, the same type of over rated forward like Henry), Huntelar should have been chosen to start. My bet on the starting 11 German forward (Close or Gomez), starting 11 Spanish forward (Llorente or Torres, hopefully Llorente), Benzema (if France gets trough), Ronaldo or Giovinco (depends on which position he will be played). Too bad Zlatan plays as a playmaker for Sweden.
