Barca were on the front foot from kick-off and Ousmane Dembele forced Inter keeper Samir Handanovic into the first of a series of fine saves with a sharp curling strike just a minute into the game.
Inter struggled to string passes together under the weight of Barca’s pressing, and Handanovic had to be at his best to stop fine efforts from Luis Suarez and former Inter player Philippe Coutinho putting the away side ahead before the break.
Icardi grabbed the equaliser at the death, taking advantage of confusion in the Barca penalty area to spin and fire home a dramatic equaliser.
Ernesto Valverde’s side, who stay top of Group B with 10 points, three ahead of Inter and six away from third-placed Spurs, go through due to their strong head-to-head record with both rivals.
