Luke Shaw is determined to prove his worth at Manchester United.
Shaw has vowed to improve and admitted he is yet to hit top form at Manchester United.
He said: "They haven't seen the best of me yet. I know I haven't been up to my full potential and I think maybe people can see that at the moment. I am trying hard and it's about getting used to everything.
"When you come to a club like this it's never easy for a young player like me. But I'll get myself started soon and put in good performances.
"I wouldn't say I've been horrendous but I know I can do much better. And I need to do better. I've come to Manchester United and I know what they need. I've been working hard and the performances will come."
