UEFA has banned Ajax Amsterdam goalkeeper Andre Onana for 12 months for a drug violation, just days after the club’s recorded signing Sebastien Haller was mistakenly left off their Europa League list.
Following a drugs test on October, 30 last year, the substance Furosemide was found in Onana’s urine.
The suspension is effective immediately and applies to all footballing activities, both national and international.
Onana has said that he mistakenly took a Lasimac tablet prescribed to his wife after feeling unwell.
UEFA has said that Onana had no intention of cheating.
“We clearly renounce performance-enhancing drugs, we obviously stand for a sport,” Ajax managing director Edwin van der Sar said. “This is a terrible setback, for Onana himself, but certainly also for us as a club.
“We had hoped for a conditional suspension or for a suspension much shorter than these twelve months for Onana, because it was arguably not intended to strengthen his body and thus improve his performance.”
It is not clear whether the error was caused by Ajax, the Dutch FA or UEFA but if the club are at fault, they will not be able to amend the situation.
