You can follow Liverpool football club for the next 100 years and I doubt you'll see a better organised team off the ball, with different strategies, than what we had under Rafa. Such top level defensive qualities mean he'll always be the man for knockout competitions, to me he's unrivalled as an organiser of teams. What we can get under Rodgers though is a set-up that may have less focus on tactics for league games, but with a more focused (and the combinations to go with it) system of keeping the ball and attacking. Rodgers is a level below Rafa as a defensive coach imo, but then again, so is Ferguson, but he's racked up the league titles. It'll be an interesting season ahead, both for Liverpool and Rafa.
