7. Changing the manager – key figures
Before managerial change, average PPG was 0.604.
Within the first 30 days of new manager, this figure was more
than doubled and achieved an impressive level: 1.214
(+101%)
Taking the first 60 days of new manager into account did not
change the results drastically (compared to the first 30 days),
so after first month trend was rather stabilized: 1.30 (+115%)

8. WRAP-UP of knowledge gained
It appears after a new manager comes, it is fine to believe
the team IMMEDIATELY 
Even better is to believe when team is playing at home,
except for Serie A
The best performers were in Germany: in Bundesliga change
of manager works.
In Spanish La Liga the teams are not doing well playing away
from home even after 2 months.
