Glen Johnson says he's joined Liverpool a more mature player than when he was at Chelsea.

"I'd say I'm more mature," he said. "There were a couple of incidents that got blown out of proportion and were totally wrong.

"That's not for me to worry about. I've put it behind me and it's not important.

"I've aged. I'm improving all the time and that has been a key factor. Before I didn't play, so it's impossible to put in performances if you don't play."

Johnson is using the World Cup next year as motivation - and it is down to his move to Pompey that he has the chance to play in South Africa.

"Joining Portsmouth was fantastic for me because I was playing week-in week-out, and working hard in training," he said.

"The most important thing for any player is consistency in playing games. That is when you learn from your mistakes.

"That is the one thing I can put my finger on.

"Liverpool are one of the big four so they will be in the spotlight a lot of more. It could be a big year. We have high hopes within the Liverpool camp. With the World Cup coming up it's a big year for everyone."
