Captain Javier Zanetti was distraught after the 5-2 defeat to Schalke. “I cannot understand what happened. There was a black-out.”
Inter took the lead after 25 seconds and were 2-1 up until just before the break, but had a nightmare second half including Cristian Chivu's dismissal.
“I cannot understand what happened. I can't even explain it to myself, let alone to you,” he told Mediaset Premium.
“We had a good start, then there was a black-out. Now we have to stay calm, look ahead and begin again by thinking positive.
“We've got to keep going, think of Serie A and then we'll go to Germany to give it all we've got.”
Many fans walked out towards the end of the game, especially as it was just three days after the 3-0 Milan derby defeat, but the Curva Nord ultras continued to sing: ‘We will never leave you.'
