Inter head coach Frank de Boer has questioned his side's mentality after they slumped to a 1-0 defeat at the hands of Sampdoria on Sunday evening.
The Nerazzurri produced a lacklustre showing in the first half, and went into the break trailing after Fabio Quagliarella's 44th-minute goal.
The result sees Inter languishing down in 11th place, with Inter picking up just three points from their last five league fixtures.
And the under-fire coach has highlighted what he believes is at the heart of their current malaise.
"This is just an issue of mentality. We have a lot of quality but we can't do much when we have the mentality I saw in the first half," he told Mediaset Premium.
"We have a problem at this moment. I said to the team during the break that we had to change and it looked like another team in the second half.
"We must forget the first half, we did not play. In the second half, yes, we played but we cannot start like this – only playing after 45 minutes. I am very disappointed with the first half."
The defeat to Sampdoria will have heaped further pressure on the former Ajax boss, but he is confident he can turn things around at Stadio Giuseppe Meazza.
"I have faith that we can change this difficult time," he added.
"As I said, I've seen a good team many times, but we must have the conviction to do it for 90 minutes, as [in the wins] against Torino and Juventus. We cannot always stay in this form."
