Manchester United striker Dimitar Berbatov is already having doubts about taking a penalty in the Champions League final.
Berbatov was on the end of some harsh criticism for a tame spot-kick against Everton in the FA Cup semi-final defeat and the Bulgarian has admitted the incident has shaken his confidence ahead of Wednesday's meeting with Barcelona.
He said: "That hurt. I'm not sure I'd step up now."
Berbatov also claimed only victory in Rome would make him feel like an equal in the United dressing room.
"I am part of this team but I don't feel fully part of it as I didn't win the Champions League (last season)," he added.
"If we can do that again this year, with me in the team, it will mean so much. I was jealous watching last year."
