Atletico have never beaten Barça from a goal down
The sides facing off at the Calderón have never taken each other to penalties in 29 two-leg ties in all competitions.
Balance: Atlético and Barça have played each other 29 times over 180 minutes: 20 in the Copa del Rey, three in the now-defunct Copa de la Liga, one in the European Cup and five in the Spanish Supercup. Barcelona have got the better of Atlético on 17 occasions to the Rojiblancos 12. In the Copa del Rey the total is closer but still favours Barça: 11-9.
Comebacks: Atlético has never won a two-leg tie against Barcelona after losing the away leg, despite having 12 attempts at doing so. In the 24 ties between the two when the first leg hasn't ended in a draw, on 22 occasions the team that won the opening leg has taken the overall tie. Only twice has there been a successful comeback: in the Copa del Rey in 1967-68 and Copa de la Liga in 1982-83, when Barça overturned a 1-0 Atlético lead on both occasions.
History: Atlético and Barcelona have played 107 times in Madrid, with 52 wins for the home side, 22 draws and 33 Barça victories. In all 341 goals have been scored, 186 by Atlético and 155 by Barça. Since the inauguration of the Calderón, Atlético have won 27 and Barça 22 with 12 draws.
One in six: Barça has won just one of their last six matches over two-leg ties in the Calderón, in 2008-09. The result was 3-1, with Leo Messi bagging a hat-trick.
More than one goal: In 61 visits to the Calderón Barcelona have lost by more than a single goal just 12 times (19 percent). The last such result was the 4-2 Liga classic in the 2007-08 season. 1-0 to the home side, which will lead to extra time, has been the outcome of seven of those 61 games. Atlético and Barcelona have never gone to penalties against each other in a knock-out tie.
Away goals: Since the advent of the away goals rule in the Copa del Rey in the 1993-94 season, 119 ties have reached the second leg with the score at 1-0 in favour of the visiting side. In 52 of them the home team were eventual winners (43.7 percent), but only five went to penalties, with two home triumphs and three away.
Messi: The Argentinean has scored more goals against Atlético than any other club in his professional career (22 in 24 games). However, Messi has not scored at the Calderón since February 2012; four matches without bulging the Atlético net.
