Pep Guardiola takes blame for Manchester City's Champions League problems
Manchester City manager Pep Guardiola said he still felt responsible for their Champions League struggles as his team start a fresh bid to win the elusive European trophy in the group stage at home to Porto on Wednesday.
Manchester City were knocked out last season by Olympique Lyonnais in the quarter-finals, making it the fourth successive time the Etihad club had failed to progress beyond the last eight.
