Chelsea boss Rafa Benitez was disappointed to see his tactics appear in the Brazilian press yesterday. The Daily Mail says Chelsea staff have been told to be extra vigilant after confidential paperwork depicting the team's tactical secrets were made public.
Scraps of paper revealing the carefully planned tactical ploys of Benitez were recovered from the floor of Chelsea's empty dressing room after Sunday's 1-0 defeat by Corinthians in the Club World Cup final in Japan.
The scrunched-up pieces of paper are said to have been retrieved by Brazilian journalists and have since been made public.
The Stamford Bridge club will not be investigating the blunder but members of the first team have been asked to be extra careful in future.
The pieces of paper show Benitez's tactics for attacking and defending corners.
