Barcelona captain Andres Iniesta has revealed his delight after his team came from behind to beat Atletico Madrid 2-1 in the first leg of their Champions League quarter-final on Tuesday night.

The hosts fell behind in the 25th minute when Fernando Torres, who was sent off in the first period, beat Marc-Andre ter Stegen, but a Luis Suarez double turned the game around for Barcelona.

Iniesta has branded his side's victory "a really good result", but is under no illusions as to the difficulty of the task in the second leg in Madrid next week.

"It's a really good result. But there is still the second leg to come and it will be as tough, or tougher, as this game," Barcelona's official Twitter account quotes the midfielder as saying.

Barcelona have now won each of their last seven games against Atletico in all competitions.
