Serie A's reputation for defence is dated but not wrong: the league still produces Europe's most tactically deliberate football, where managers game-plan for specific opponents and match state dictates behaviour more than anywhere else.
For bettors that means context beats form. A side protecting a Europa place away from home plays a different sport from the same side chasing a derby. Totals swing with motivation; BTTS pricing often lags the reality of mid-table matches that open up late.
Promoted sides in Italy historically stabilise faster than in England or Spain — the tactical floor is high — which the market has been slow to fully price in early-season handicaps.
