Luis Suarez scored two superlative goals as Barcelona beat Inter Milan 2-1 in a thrilling Champions League Group F encounter at the Camp Nou on Wednesday.

Lautaro Martinez got the visitors off to a flying start after just three minutes when he pounced on a ball behind the defence and slotted his left-footed shot past Marc-Andre ter Stegen while under pressure from Clement Lenglet.

His goal marked the fifth time Barca have conceded a Champions League goal within the opening five minutes of a match and the first goal Inter have ever scored at the storied stadium in four tries.

Barcelona piled on the pressure shortly after, however, but could only force a handful of straightforward saves from Inter goalkeeper Samir Handanovic.

Inter thought they had a second in the 27th minute when Antonio Candreva was found free on the right wing before beating Ter Stegen at the near post but he was rightly flagged for offside.

Barca then needed separate blocks from Nelson Semedo and Ter Stegen to thwart promising Inter attacks soon after as the Italians ended the half looking the more threatening side.

Despite Inter looking the better side, Suarez levelled the score in the 58th minute with a sensational scissor-kick volley from an Arturo Vidal cross -- the Uruguay international firing from the edge of the 18-yard box and leaving Handanovic no chance in the Inter net.

He capped his brace in dramatic fashion six minutes from time, smartly pushing a square ball from Messi through a thicket of defenders at the top of the box and beating a late-arriving Handanovic with a low dragged shot.

The win gives Barca four points from two matches in the young campaign, while Inter have taken just one.

Ernesto Valverde's men will next visit Slavia Prague on Oct. 23 and Inter will host Borussia Dortmund that same day.
