I train the team on three sets of tactics - currently 4-3-3, 4-5-1 Asymmetric and 4-4-2. Generally, I will stick to one tactic for as long as it's successful but certain opponents require an alternative approach and sometimes I switch tactics during a match if I want to get two upfront or if my on-coming substitute suits the other system better. Sometimes I make subtle changes, like changing the BWM to a DM because it suits the sub or moving my left winger to the right to play as an Inside Forward, without adjusting the rest of the team's set-up.
