Ranieri said that he was happy with Tiago's recent displays and that he would be looking to play him more. In Camo's absence, the best opportunity is Tiago in a flat 3 man midfield with Nedved in front of that.
This way, Ranieri doesn't have to chose between Tiago and Nocerino, and Nedved can run more freely between the lines. Tiago would be allowed to go a bit more forward with Nedved probably moving more to the left, as he likes to do.
The fact that Marchionni, Brazzo and Palladino haven't convinced as right wingers should push Ranieri to use this system; it also remains to be seen if Iaquinta is fit enough to start to do a full 433. If he is, Tiago would be the one dropped out I guess.
