The Viola managed to beat Torino 4-1 on Sunday in the Serie A.
“We have to remain firm and focussed as the league begins to heat up and I think fourth place will be between us and Roma,” Mutu told La Nazione.
“We have proved that we can do it. The Champions League exit still hurts us but it’s everyone’s fault for it because we could have done more.
“However, we have to be patient. Hopefully we will play more in it next year. Now we have to focus on the league and aim for the UEFA Cup and then if we do better than that then it will be important.”
