Sarri on Guardiola's advice in December: "He told me you have to work only on 14 players otherwise you are in trouble. You need too much time to improve all the squad."
Remember De Bruyne telling me: “We only train tactically 15 mins per day. But we learn to switch between different systems: 3-4-3, 4-3-3, 4-4-2, 3-6-1...”
