Hannover's players have been asked to disclose their sexual interests as part of a survey designed to help their coach understand them better.

The psychological test, to be undertaken on a voluntary basis by the Bundesliga club's squad, includes statements such as: "I am what you could call sexually unrestrained"; "I want any sex I can get" or "I have a lot of erotic fantasies", which players can evaluate on a scale of -3 to +3.

The club's coach, Mirko Slomka, said he had already completed the 128 questions, and the players were free to see his responses if they wanted.

Slomka told Bild: "With this test I know how I can best reach each player."

The club said participating in the Reiss motivation profile, developed by the US psychologist Steven Reiss, was voluntary. Any answers received will then by evaluated by a the club's "motivation consultant" Peter Boltersdorf.

According to the Reiss theory, humans are driven by 16 basic desires, and the test will highlight each individual's core values and goals.

Boltersdorf said: "Each player needs different conditions to perform at his best over a long period. This is what I have to look into. Every player should have the feeling that his individuality is being considered."
