Lee Cattermole is confident about his form this season with Sunderland.
At 26, England hopeful Cattermole believes he has settled down, on and off the pitch.
"You just grow up a bit don't you?" he told the Daily Mail.
"What is important is that you go through ups and downs and eventually you work out what helps you bring about a consistent level of performance. That's what I'm trying to do. I'm trying to find that consistent level for 30 to 35 games.
"I don't want to be the best player one week and the worst the next. I'm trying to be a good solid performer every week. I feel I'm at that level now.
"I think that is all down to being a bit older. I am 26 now, no longer a 20-year-old. I've been around a long time now as I was in the first team at Middlesbrough at 17. I just think sometimes you are just not old enough to be in the position you are in. It takes time to figure out things yourself."
