UEFA will implement mandatory blood testing for players next season across all European competitions as part of strengthened anti-doping efforts. Players may now be subject to both urine and blood samples for doping controls and will need to provide their locations for out-of-competition testing. These new rules follow a UEFA panel meeting where it was acknowledged that doping cannot be said to be absent from football, so continued vigilance is needed. UEFA will also analyze steroid profiles from samples of nearly 900 players over several years to identify potential prevalence of steroid use anonymously.
