Banana flank
In football usage, a banana flank is a flank in front of the opponent's goal with a strongly curved trajectory. To do this, the ball is kicked out of play with spin .
technology
The banana flank is carried out by the so-called internal clamping joint. The executing foot “wipes” the inside of the ball past the ball and causes the ball to rotate sideways. The ball is roughly hit with the big toe (see toe bones or foot skeleton ). After hitting the ball, the foot swings, it practically “guides” the ball a little longer. This also adds to the rotation.
The curved trajectory that the ball describes on the banana flank is created by the rotation of the ball. It pulls air with it, in the direction in which it turns ( Magnus effect ). The ball is accelerated by the player to around 100 km / h and rotates around its own axis around eight times per second. Turbulence also plays a role in the effect.
Such flanks were first struck in Brazil, the inventor of Arthur Friedenreich from São Paulo. After his active time, Didi , director of the Brazilian team at the 1958 World Cup in Sweden, had particularly impressive appearances. In German professional football , the banana flank was hit particularly skillfully from the outside in by Manfred Kaltz . In the late 1970s / early 1980s, Kaltz's banana flanks not only hit the head of Horst Hrubesch at Hamburger SV , but also briefly achieved something of cult status (one of Hrubesch's words was: “Manni Banane, I head, goal”). Others also attested Gert "Charly" Dörfel to have been a skilful banana flanker. This had thus served in the national team as well as at HSV, especially Uwe Seeler as a template.
