"I wish to repay Liverpool's efforts to sign me on the field. I want to gain the respect of the Liverpool players in training and win a place in the team on merit," said the midfielder.
"Now, a new door is open and, as always, I will get my head down and fight for a place in the team. If I don't play, I am not happy."
"I wanted to prove to myself that I can play in England. I've not been on the pitch enough yet to know if I can.
"Now, there is a chance to play in a top team and fight for a place in the team with great players like Steven Gerrard or Xabi Alonso. It's a fantastic challenge."
