Manchester City’s dominant position at the top of the Premier League ahead of Sunday’s trip to champions Liverpool has been built on the solid foundations of an impenetrable defence. 

Pep Guardiola’s men have conceded just two goals in their past 13 league games, winning nine in a row to open up a seven-point lead over fourth-placed Liverpool, with a game in hand. Liverpool took City’s crown as champions last season, romping to a first league title in 30 years.
