Horst Hrubesch (born April 17, 1951 in Hamm) is a retired German football player and currently employed as a youth trainer at the DFB. His nickname was Das Kopfball-Ungeheuer (the Header Beast) for his incredible heading skill. Standing at 189 cm and gifted with great physical strength, Hrubesch was one of the most lethal centre-forwards of his generation.

Hrubesch was the typical latebloomer. He played in small clubs until the age of 24 before he was signed by Rot-Weiss Essen. There, he played well enough that Hamburger SV bought him. There, he blossomed into one of the most dangerous and intimidating forwards of the Bundesliga and was soon called up for the German national team. Hrubesch was known for his symbiotic relationship with fellow HSV player Manfred Kaltz, a right wingback whose clockwork-style crosses Hrubesch often headed into the goal.

His greatest successes were the win of the European Championship in 1980, where he decided the finals with two of his late Ungeheuer header goals, and 1983, where he won the Champions Cup against Juventus Turin. He also was German champion in 1979, 1982 and 1983. He scored 136 goals in 224 games in the Bundesliga and was capped 21 times.

After his successful career, Hrubesch became a trainer and has several less successful stints in the Bundesliga before starting as a youth coach in the DFB.
