Brazil legend Roberto Carlos has been the subject of an unprecedented incident which forced him to sign an autograph during a Russian league game with his new side Anzhi. The 38-year-old, who joined the Russian side in February, was surprised to see the invader running at him with a pen and a paper asking for his signing during the match with mid-tablers Volga. The fan was delighted when Roberto Carlos calmly granted him his wish as no one came to came onto the pitch to deny the invader. Anzhi eventually won the game 2-1 to remain level on points with leaders Kuban, eight weeks after the start of the competition. Robert Carlos on-field autograph
