Thanks for the welcome and agreed with the first paragraph, however him being able to cross, that would require him to be a winger in which is not meant for him. In which you basically said that, the fullbacks are the most important factor for a 4-2-4 because without them, everything would fall a part. However, due to our system requireing ball possesion, all that comes from Pirlo's position in which is the important factor of our philosphy of play. Now as for Lich, him being a fullback he is one of our most important players with duties, his defensive duties, work rate and going forward has been fine, even supporting Krasic at times, but his other duty requires him to cross the ball well, just like any fullback is requeried. Take for instance, Abate from Milan, works hard, defends great, but him crossing a ball is just horrible in which is his fail. Now of course Lich can improve, and hopefully he does that fast. Speaking of wingers, that can also be said about Pepe, who I also see some what failing crosses, but his performances have past my expectations, same goes for Giach, but I hope Giovinco comes back nonetheless and/or Elia adapts to Italian football and can play over his place.
