Inter Milan coach Andrea Stramaccioni has accepted the blame for his side's 4-1 drubbing at the hand of Fiorentina on Sunday, admitting he should have made a number of changes.
Inter looked a changed side from the one that defeated Cluj 2-0 in the Europa League on Thursday, although Stramaccioni believes his players should have been capable of backing up that performance.
"I think it's all too easy to read this match, aside from Fiorentina's merits," he said. "We played two games with more or less the same players, but I never imagined a game like this. I saw my Inter were really tired and struggling. I thought we'd pay a small price for the fatigue, but not to this degree. I evaluated the situation incorrectly.
"We intended to have Fredy Guarin on David Pizarro, but our two internal midfielders were struggling and he had to drop back. It was an adjustment, but the defeat was clear.
"We could've done without this defeat, but I don't know how we can play so differently from Thursday to Sunday. Maybe I made a mistake. Inter were too ugly to be true."
Inter face another difficult week with the return Europa League fixture against Cluj in Romania and a derby clash with AC Milan on Sunday, although Milan host Barcelona in the Champions League on Wednesday to relieve some pressure from Stramaccioni.
"We have to take those fixtures into account," the Inter boss said. "Never more than tonight was everyone's performance below par. We paid an exaggerated price for the two games.
"We must absolutely get back on our feet. We are honouring the Europa League and that takes away energy, but I don't mean that as an alibi."
