that`s the plan mate. If we do get a nice left winger for a starting role, Delneri will change his tactic, so both the new LW and Marchisio will be on the field at the same time, along with key and indispensible players - Krasic, Melo and Aquilani.
I just cant see Marchisio benched, hes got his place on the field, and if the new LW is a better winger than him, I expect to play with a three man midfield with Melo-Marchisio-Aqua, and actually I dont see that as a big problem, we`ve got maybe the best midfield in Serie A (if not the best, definitely in top 3), with a new gifted and powerful winger like Krasic on the other side we will be even stronger, we will only lack a true goalscoring machine and a strong fullbacks, but hey, that should be more than enough to finish in top 3...
