Alexis Sanchez scored and was sent off on his first Inter Milan start but his side maintained their 100% winning run in Serie A by beating Sampdoria.
Sanchez, on loan from Manchester United, deflected Stefano Sensi’s shot for the opener, then tapped in another.
But he received a second yellow card early in the second half for an apparent dive inside the box.
Jakub Jankto pulled a goal back, but Roberto Gagliardini added the third for Antonio Conte’s side, who stay top.
