A photo by the private Agencia Estado news service depicts Ronaldo showing his middle finger to fans as he was leaving the stadium on Wednesday after the 1-0 defeat, a result that left the club in danger of not advancing to the semifinals.

Local media say about 30 fans cursed and shouted at Ronaldo as he was about to enter a car to leave the Arena Barueri. Some called him fat.

Ronaldo had said on the field he made some “childish” mistakes, but was ready to handle the pressure from fans.

Corinthians is in fifth place. The top four advance.
