It seems like every club has that one signing from a Brazilian team that looks fishy. Sueliton Pereira was to Rayo what Douglas is to Barcelona. On 2 June 2011 it was announced that 25-year-old Sueliton was joining newly promoted La Liga side Rayo Vallecano as the club's first signing for the upcoming La Liga season. He wasn't a nobody - he was signed from Campeonato Gaúcho side São José EC where in his one season with the club, he appeared in 13 matches and scored 2 goals, being selected as the best right back of the competition. However, he failed to appear in any league matches for Rayo, and rescinded his link on 20 December 2012. He is the exception to the rule though - at Rayo Brazilian footballers have thrived. I've obviously written about Diego Costa before ( here ): It's funny to think that Diego Costa was once a backup at Atlético Madrid. In June 2011, he was packing his bags. Beşiktaş had agreed a deal, and he was going to leave. All the papers...
