The best example is Pep at Barcelona; Xavi, Iniestra, Messi..No need to do much thinking about tactics there..
In my heart of hearts I knew that Holgate had to play but how if Coleman had to play too? Solution: go with 3 at the back. Coleman bombs up and down the flank all afternoon and Holgate brings speed and a bit of aerial ability to the defense.
Maybe against a packed defense at home you might play an out and out winger but surely the team now has finally got a style, a way of playing that has been lacking all season. And I reckon RK got there by finally picking the best players and letting the formation sort itself out namely no more Jags, Cleverley, The Stek, Miralles on the wing..
