Inter lost the match 0-1 after a late Daniele De Rossi penalty.
Mancini told the Inter Channel: “We didn’t play well. They were better in the first half, but we dominated the second half until they snatched a goal.
“We made too many simple errors, especially when we won the ball back in midfield. We’re not yet
fully fit and that caused us to make mistakes we would not usually make.”
