Herein lies our problem. When asked to play the Rico role, John Stones said he had to ask Rico how to do it.
The inverted RB was in vogue a couple of seasons ago, but I can't think of a team we've faced or that I've seen recently bothering with it.
It seems we have a choice to make. We either find a Rico clone, or we change our RB strategy. It's one or the other, & I'd prefer the latter which would open up our RB options, plus give Pep the option to revert to his preferred system with Rico if deemed absolutely necessary.
