Belgian side Anderlecht resumed training under strict social-distancing guidelines on Wednesday prompting criticism from medical experts.
Despite the Belgian first division being cut short by the coronavirus pandemic the Brussels club elected to go back to work "for those players who want to".
Among those to question Anderlecht's decision was virologist Marc Van Ranst who described it as "legal but a bad signal" during lockdown.
Another doctor wrote to the Brussels mayor telling him: "It's incredible. (It) goes totally against government recommendations and the advice of experts."
