The Nerazzurri have lost both their games against bottom of the table Siena this season and saw Cristian Chivu sent off at the Stadio Artemio Franchi.
“It is without doubt an ugly defeat and we are very angry,” said the Coach. “We had a few players missing, but there are no alibis for a poor performance.
“Despite the fact we lost, we are still only three points away from the Champions League places, so we cannot give up and have to keep fighting. We can still achieve our objective.
“We’ve got to find ourselves again, as we are still the team who in November were a point off the leaders and had great ambition. We are going through a difficult moment, but I am sure we will get out of it.”
