Everton midfielder Ross Barkley has admitted to being below his best this season, but thinks he will be stronger for the experience.
The 21-year-old established himself as a regular at Goodison Park in 2013-14 as they finished fifth in the Premier League.
His form was good enough to win him a place in England's 2014 World Cup squad, but he has struggled for form since.
Barkley has scored only twice this season for an Everton side who are 13th in the league ahead of Saturday's home match against Southampton.
"From my point of view I haven't done as well as I know I can, but things like this happen," Barkley told Premier League World, a television show made on the competition's behalf for international broadcast.
"You have to go through bad days to get to the great days you have in your career.
"Everything's a learning curve. We haven't been going through the best period at the moment but we're going to come through this and be really good at the end of it.
"I don't feel pressure. I believe in myself and I know what I can do. It's not me feeling pressure, it's just me putting pressure on myself if I don't do my best, and I know I can do better.
"I just focus on getting better every day, putting things right in training and then hopefully what I'm doing right in training I'm going to show in games as well."
Barkley has played in a number of midfield roles this season, but sees his long-term future as a centre-forward.
He said: "I'm a striker. I feel I can have my greatest impact there because I'm free to roam around the pitch, take players on, have shots and create chances."
