When you say he can't cross you're exaggerating, the four full-backs can cross, players who can't cross are Motta, Molinaro and sometimes Grygera.
Lich hasn't been as good offensively as he he was last season, because he's played in a 4-1-3-2 formation most of the times and not 3-5-2. But he's still awesomely good, he shut down Real's flank, Dortmund's flank and has been solid for most part of the season.
