RIO DE JANEIRO, April 3 (Reuters) - Former Real Madrid and Brazil coach Vanderlei Luxemburgo's Palmeiras team chalked up their ninth win in a row when they thrashed Central 5-1 away in the Copa Brasil on Wednesday. Forward Kleber and Chilean midfielder Jorge Valdivia gave Palmeiras a 2-0 halftime lead in the second round, first leg match. William pulled one back direct from a corner in the 56th minute before Palmeiras added three goals in the last 10 minutes, one from Martinez and two penalties converted by Alex Mineiro. The win took Palmeiras straight into the next round as the away team qualify automatically if they win the first leg by two goals or more. Gremio went down to their first defeat of the year in their 18th match when they lost 2-1 to third division Atletico Goianiense. Juninho scored for Atletico in the 21st and 49th minute and Roger pulled one back to give Gremio a valuable away goal. Botafogo also lost to third division opposition as they were beaten 2-1 by River. Kemerson scored the winner six minutes after half-time.
