This time, I decided create two main tactics: One, from his time at Barcelona; and one from his time at Barcelona and Bayern. The tactics are great at creating overloads like Bayern in real life; the tactics have terrific ball movement and constant position swaps so as roaming; the tactics employs high tempo (not to be confused with the TI!); The defensive line is very high; Players need speed and stamina, because of the intense pressing, that the tactic uses; your team needs to be good both technically and mentally -- otherwise the tactics are to adventurous -- and I advise you to take a more conservative approach, playing more simplistic and organised.
I've also included some counter tactics against tough opposition or/and to use in later stages of the match. I used it against Tottenham away, image below...
As far as training goes: I use some very intense schemes, always use high to very high intensity -- but, let your players rest when you play a lot of games in a short period of time. Fitness is very important however you want play.
