Lucas Leiva believes his performance in last night's victory over Portsmouth was his best in a Liverpool shirt.

"I feel I have adapted to English football and I can play much quicker in games now," the Brazil midfielder told liverpoolfc.tv.

"I was getting into the box and also had a few chances to score against Portsmouth, so I am happy and I am trying to improve every day.

"I think it was my best performance for the team."
