Agreed. But whatever you say, still they're playing in a same position, but have some different roles. It's still hard to imagine that two player like this are playing together.
I understand what you said, but my elicitation is that they are two striker with different abilities, but with a same role, their main task is the same.
His my last option however. (Of course if we don't count players like Borriello an 'option'!)
