Pepe not being "great" ran the fuck out of the left side of Fiorentina all game long. It's incredible how well Licht does when he doesn't have a player like Krasic clogging space in front of him. Pepe opened up space for others (like Licht) to move into. You could see how easily it worked with some of Vidals thru balls in the first half.
That's how you win. Make space for others, do the simple things right, and run your socks off.
The simple things.
