Inter took a third minute lead when Sneijder fired home an unstoppable shot after collecting Maicon's pass but Roma levelled 10 minutes later when Simplicio turned in Marco Cassetti's cross.
However, the home side went into the break 2-1 ahead when Eto'o fired a shot that slipped through the hands of goalkeeper Sergio.
