After a 2-1 away victory in the first leg, there had been little doubts about Osasuna advancing ahead of the return leg and so again some key players, among them Javad Nekounam, were rested.
Shojaei, currently only a substitute in La Liga, this time earned a start and thanked coach Camacho by showing a good performance and assisting Dady's 79th minute goal with a pass into the box.
Shojaei and Osasuna had had a less entertaining weekend before the game, when they had suffered a 0-2 away loss to Almeria.
While Nekounam had played the full 90 minutes, Shojaei had come on 17 minutes from time, however, could not prevent his team from losing.
