Romelu Lukaku scored on his Serie A debut for Inter Milan as they convincingly beat 10-man Leece.
The Belgian striker, signed by Inter for a club record 80m euros (£74m) from Manchester United on 8 August, tapped in the third goal in the 60th minute.
Marcelo Brozovic curled Inter’s opener and Stefano Sensi’s drive made it 2-0.
Antonio Candreva’s 30-yard drive completed the victory after Leece’s Diego farias had been sent off for a nasty looking challenge.
Lukaku, who hit 42 goals in 96 games for United after joining from Everton for £75m in July 2017, has now scored on his league debut for each of his past four clubs.
