Good post! Sums it up well, I think (with my limited knowledge).
Would it be beneficial if tactics could change depending on who was considered the main man? Build a tactical set up around each of them (even when the others are on the pitch) and let them play freely, with others supporting? Are they each good enough to handle that?
It would offer different tactical options? Kind of like an American Football type of approach.
What thinkst thou?
