Inter Milan GM Beppe Marotta admits there's frustration after defeat at Bologna.
The result saw Inter miss the chance of overtaking AC Milan at the top of the Serie A table.
Marotta said, "It is clear that as a sportsman I smile, but it is a bitter smile.
"It's part of the game, we lost a battle but not the war. We have to get back together as quickly as possible, we are p***ed off but not depressed.
"There are 4 games left, let's see what happens. Today's football is not taken for granted as in the 70-80s. Even the team that has nothing to say can win today."
