#4 AS Roma
Much like Dortmund, Roma employ a counter-attacking based formation with the likes of Radja Nainggolan, Kevin Strootman (when fit), Danielle de Rossi and Miralem Pjanic looking to release the likes of Mohamed Salah and Stephen El Shaarawy.
Yet while Roma may simply seem as a counter-attacking style, they equally frustrate opponents with the ball at their feet. Ronaldo, at Real Madrid, is not the kind of player who would dance around players with quick and short passes, he prefers the direct counter-attacking style that we're so used to seeing from the Los Blancos.
With incredible passers in the mould of Pjanic and De Rossi, Ronaldo would thrive making those diagonal runs from the left wing. The Portuguese has always known to link up with an excellent passer of the ball and Pjanic might be the kind of player he could use to exploit opposition defenders.
