Inter Milan coach Antonio Conte snapped at reporters after their 0-0 draw with Shakhtar Donetsk.
Inter finished as bottom of their group, so miss out on Europa League qualification.
Conte warned reporters afterwards: “You can have your opinion, I respect that. I do not agree, because I think the team gave all it had, did all it needed to. It's incredible that over two games that we dominated against Shakhtar, we didn't score a single goal.
“I don't agree we lacked determination at all. My players gave their all tonight, so I absolutely do not agree.
“We have to evaluate everything with cool heads, not after an exit like this. There is a great deal of regret and disappointment, but I absolutely do not feel we were lacking determination, focus or aggression.
“We lacked a goal and throughout the Champions League campaign, we have not been fortunate with referees and the VAR. If you go back and look at all the situations that were not seen or evaluated, then…
“Having said that, there is disappointment because we had the chances, but if you don't score goals, you don't win."
He added: “Shakhtar came here and transformed their tactics against us in order to neutralise us. They lost 5-0, so that's why they changed. Think before asking questions!"
