Manchester City know only too well that this is how you beat Manchester City. Defend with a low back line, narrow the pitch and break with real bravery.
In that sense, Marcelo Bielsa had Pep Guardiola's number. But then again, it is not a secret. Leeds made sure to keep their full backs tight in the defensive third, forcing City to attack wide.
City do not like attacking a low block from wide areas because they do not have a striker who can outmuscle Premier League central defenders aerially.
