Inter CEO Beppe Marotta insists Romelu Lukaku is not for sale this summer.
The Belgian continues to be linked with Europe's biggest clubs after scoring 24 goals in 36 games for the Nerazzurri last season.
Chelsea and Manchester City have both been linked to the 28-year-old.
Speaking to Sportmediaset ahead of a friendly with Pergolettese, Marotta said: "From our side, we can yes absolutely, Lukaku is not for sale.
"Lukaku is an important piece on the chessboard available to Simone Inzaghi."
