get a book about "football tactics 101" or something.
when we play vucinic and giovinco our tactic is the following.
vucinic draws himself back a bit to be closer to the midfield. in doing this he draws his marker with him, leaving space where that marker was before. giovinco making the lateral movement running into that space that is now unoccupied.
there are two possible scenarios which arise from this:
1) giovincos marker follows him, leaving a blank space himself, where a midfielder can run into
2) giovincos marker playing "room/space marking" and staying where he is, where marchisio or another midfielder of us drives forward and plays the triangle: vucinic->marchisio->giovinco (who is either unmarked or only marked by the full back of that side)
