Romelu Lukaku marked his Inter debut with a goal against Lecce and the striker revealed he was motivated by a moment of pre-match magic.

A club-record signing from Manchester United, the Belgium international took 60 minutes to open his Serie A account as he tucked in the rebound after a long-range Lautaro Martinez shot.

The goal helped Inter to a 4-0 victory in Antonio Conte's first match in charge, but it seems the club's marquee addition saved his absolute best for the warm-up.

Former Everton forward Lukaku shared a video on social media of a thumping strike he sent whistling into the top corner during the build-up to kick-off at San Siro.

The 26-year-old tagged the footage: "When I knew it was meant to be..."

Marcelo Brozovic, Stefano Sensi and Antonio Candreva scored the other goals in the Nerazzurri's big victory.

In a separate Twitter post, Lukaku wrote: "I'm happy with today's win. Forza Inter."

Conte lobbied hard for Lukaku's signature during the close season and praised the "gentle giant" for his immediate impact following the Lecce match.

Inter, top of the table after one game, next face Cagliari on Sunday.
