Kyle Walker is still striving to improve his game despite an impressive season for Tottenham.
Walker made more appearances for Tottenham than any other player this term and helped Andre Villas-Boas' men to a fifth-place finish, a point behind Arsenal.
Nonetheless, the 23-year-old admits he berates himself if he does not reach the highest standards.
"I set myself high standards last season and I'm pleased I did, but once you set those standards, if you then fall below them people start to get on your back a little," Walker told Spurs TV.
"But I'm the first to have a word with myself and say I 'could do better'. I've played 100 games in two seasons - that's a lot of games - and it took a while to get in the team.
"I was patient, got my chance last season and I have to keep doing the things that got me a chance in the first place. I want to win things here.
"If I've had a bad game, I'm straight home and it gets to me. I shouldn't let that happen but I'm passionate and want to win things.
"I want to play to the best of my ability and anything below means that I'm not happy."
