Inter opened their Serie A title defence in commanding style by thrashing Genoa at the San Siro.
Milan Skriniar settled nerves with a sixth-minute header to give new boss Simone Inzaghi the ideal start.
Summer signing Hakan Calhanoglu swept home a stunning second minutes later after Edin Dzeko’s clever lay-off.
Arturo Vidal and Dzeko then scored second-half goals for the champions, who were irresistible and look set to challenge again this season.
It has been a difficult summer for Inter, the joy of a first Scudetto for 11 years was followed by the high-profile departures of manager Antonio Conte and star striker Romelu Lukaku.
Conte’s champions were built on a rugged defence and clinical finishing on the counter but early signs suggest Inzaghi will take a different approach.
On this evidence, his Inter will seek to dominate possession and create space with electric movement – something they achieved impressively throughout.
Turkish playmaker Calhanoglu is a steal after controversially joining on a free transfer from city rivals Milan and he ran the game, an offside flag denying him a second goal on debut.
