Atletico draw Barca in Cup semi thriller
The last time the pair met in the Copa del Rey, Barcelona won and went on to lift the trophy in 2015.
Celta Vigo drew Alaves in the other home and away semi-final to be played February 1 and 8.
The most recent cup meeting between Barca and Atletico saw the Madrid outfit win a Champions League quarter-final (1-2, 2-0) last April.
The last time the pair met in the Copa del Rey, as the Spanish Cup is named, Barcelona won (1-0, 3-2) and went on to lift the trophy in 2015 which they successfully defended last season.
Atletico were La Liga champions but lost the first leg of the 2015 semi 1-0 in Catalonia before an explosive return that featured 11 yellow and one red cards before Neymar's brace saw Barcelona win 3-2 on the night.
Antoine Griezman's double for Atletico in the Champions League return leg in 2015 clinched an equally controversial cup tie.
In the midweek quarter-final Barcelona completed a 6-2 aggregate rout of Real Sociedad while Atletico beat Eibar 5-2.
The major surprise of the quarter-finals was Real Madrid's 4-3 defeat by Celta Vigo, while Alavas beat second tier Alcorcon.
