Professional football leaves us with negative news about the use of performance-enhancing substances in sport. The latest: Nagoya Grampus player Jakub Swierczok.
The Polish international was banned by the Asian Football Confederation after testing positive for a doping offence.
Swierczok will be banned for four years for testing positive for 'A' and 'B' samples.
The player spoke quickly about this: "The nutritional supplements contained those substances but they were not listed on the label."
