Real Madrids biggest challenger at the Club World Cup will be a team with a Brazilian coach who says he played better than Cristiano Ronaldo. European champion Madrid and South American champion Gremio, coached by former Brazil forward Renato Gaucho, are the favorites for the tournament featuring the champions of FIFAs six continental confederations and the host nations league winner. Renato Gaucho, a star for several Brazilian clubs in the 1980s and 90s, made headlines across Brazil not long ago after saying that for sure he played better than the Portugal star. I wanted to see Cristiano Ronaldo playing for the teams that I played in my time, many not paying salaries for three or four straight months, and to be a champion like I was,the brash coach told ESPN Brasil earlier this year.I wanted to be playing for Real Madrid today, playing once a week, on great fields, and with the teammates that Ronaldo has. I really wanted to see that.
