Inter coach Andrea Stramaccioni believes his side's season has been "cursed" with injuries and refereeing decisions.
The Nerazzuri find themselves in seventh place following their 2-0 loss to Cagliari on Sunday and the 37-year-old is no doubt as to the cause of their slump.
"The key was yet another injury in this cursed campaign, as we lost Walter Gargano. His absence made us lose something in terms of balance," he told reporters.
"Yuto Nagatomo then came off the bench and got injured again after three minutes, so we've lost another two players for Wednesday.
"Any side that loses two forwards [Antonio Cassano and Diego Milito] to injury and other big players would struggle to do well."
Stramaccioni also questioned the performance of the referee arguing that Cagliari could have had a man sent off and that the penalty awarded against his side was unfair.
"There was a dubious incident on Tommaso Rocchi in the first half, which would’ve been a red card for stopping a clear scoring opportunity," he continued.
"Today the referee was conned by [Mauricio] Pinilla, whereas last week with Atalanta there was nothing there at all. It really is a cursed campaign, how can you give a penalty like that?"
Inter have a chance to salvage their season with a Coppa Italia semi-final with Roma on Wednesday. The Giallorossi lead 2-1 from the first leg.
