Coentrao signed a six-year deal with Real yesterday.
"It's the dream of any player. Since childhood I imagined playing in this team and it has become real," he smiled.
Coentrao welcomes the battle for a left-back berth with Marcelo.
"Having the team of quality players like Marcelo is good for the group. I will work hard to play and so will he. We will compete for a spot every week and it will benefit the team."
