With the Rome derby looming, Petkovic feels his players weren't on the case.
â€śI consider myself the first person responsible for this defeat,â€ť said the Coach. â€śUp until the first goal we werenâ€™t doing too badly, but our attitude after the second was inexplicable.
â€śI just hope the derby was not already in the minds of my players. It is an important game, but itâ€™s still a week away.
â€śI substituted Hernanes at half-time because he was not playing well. We kept up the tempo, but did not perform. Itâ€™s a psychological issue.
â€śThe Rome derby is very important, but before that there is the Europa League.â€ť
