The have SO many players capable of scoring, I think the 1 striker thing is a bit of a red herring, as a lot of modern teams play with these new-fangled wing striker type players.
Agree about the striker thing. A lot of odd modern teams play with this 'false 9' thing including Germany against Portugal. Why bother with strikers when you have a heap of players who are able to score? It is a crying shame Reus got injured as he is another midfielder who can score for fun.
