Ross Barkley said his penalty miss in Chelsea's 1-0 defeat to Valencia would not have kept him from taking another spot-kick because he swiftly brushed off the disappointment.
Frank Lampard's men fell behind to Rodrigo Moreno's 74th-minute strike in the Champions League clash at Stamford Bridge, and the Blues boss sent Barkley on as a substitute six minutes later.
The England international had been on the field for just seven minutes when his side won a penalty and he stepped up despite Willian and Jorginho both appearing to stake their claims to take it.
Barkley's spot-kick grazed the top of the crossbar on its way over and Chelsea began its European campaign with a defeat, but the midfielder dismissed concerns about the moment, saying: "If there was another penalty in the game I would have been confident of taking it.
"You can miss penalties. It's not the end of the world.
"We've got five more group games to go that we're aiming to win."
While backing himself to convert penalties in the future, Barkley said his team-mates were not vying to take the kick before he stepped up.
"We've got a lot of good penalty takers in the squad," Barkley said. "On a sheet in the changing room, it says I'm on penalties when I'm on the pitch, otherwise it's Jorginho.
"All players feel confident of taking penalties, but we can all miss them. It's more 'good luck with the penalty' type of thing, encouraging me. They would have been willing to take it as well, but I felt confident.
"They were just encouraging me, encouraging me to score the goal. They are confident of taking penalties as well, but I take penalties every day.
"I don't miss them in training and in pre-season I was scoring penalties. I've missed penalties before, when I was at Everton.
"I'm gutted I missed, but these things happen."
