Pep Guardiola is one of the greatest ever coaches, but did not “do his homework” on English football, according to former Chelsea manager Avram Grant. Guardiola is set to end his first season at Manchester City without a trophy, the first time he has failed to collect silverware in a campaign. The Catalan, who has won six league titles and captured the Champions League twice, was hailed by Grant despite his City side sitting 14 points behind league leaders Chelsea.
