Man City success is a ‘mystery’ - Pep Guardiola

Manchester City manager Pep Guardiola said that his team's success in the current Premier League season is a 'surprise' for the Spaniard himself. Guardiola's side stretched their lead at the summit to 11 points with a 2-1 win in last Sunday's derby at Old Trafford – an advantage they consolidated by beating Swansea City 4-0 in midweek.
