"It's an honour when I am compared to Roberto Carlos," said Santos.
"I was always a fan. I played with him for three months at Fenerbahce and he's a great friend, who's always ringing and texting me. In Turkey, he played at left-back and I played in front of him - I scored 13 goals that season. We are similar players but it worked playing in the same team.
"I'm a left-back, though, that's my position. I wasn't as happy as a winger. I like to receive the ball and see the whole pitch in front of me. Although I've always been a goalscorer, even as a left-back."
