Fabio Coentrao is determined to live up to his price-tag at Real Madrid.
Coentrao cost €50 million less than international team-mate Cristiano Ronaldo but nevertheless feels he has something to prove.
He told AS: "I always hear about the 30million...they say it's expensive, but I cannot answer this question. Time will tell. I have the certainty that I have the quality and I want to show everyone why they paid 30million.
"I have to prove to everyone that I have the qualities to be here. I am certain that I will respond in the future to this question and that it was worth paying the money for me."
Coentrao revealed he had received a warm welcome from his new team-mates.
"It's a fantastic group. I am feeling well, and not just because of the Portuguese and Brazilians here," he added.
"I feel great in this group. It is a fantastic club and a team with high quality. I am proud to be here, but I have to work hard from now."
