Internazionale coach Roberto Mancini says his players have to play a good game if they are to beat Dnipro Dnipropetrovsk on Thursday.
The Nerazzurri are strong favourites to win Group F of the Europa League with the Italian determined to make it through to the next stage of the competition as group winners.
"In the derby we produced a number of nice things but also some mistakes," Mancini said.
"I was happy with what the team produced during the 90 minutes.
"[Tomorrow] we have to win the game to win the group.
"Dnipro are strong away from home, they play aggressive football and have technical and physical players in their team.
"They are dangerous from set-pieces and on the counter. It will not be easy, we have to play a good game to beat them.
"This season the Europa League is even more important, it's not taken in consideration before the Last 16 or Last 8 but then it gives you the change to win a trophy and to play the European Supercup."
