Lyon president Jean-Michel Aulas has hit out at Ligue 1 for ending the season prematurely, bemoaning that it showed a lack of leadership in every shape and form.
The season was concluded on March 13 due to the coronavirus pandemic which led to Paris Saint-Germain being named the 2019/20 season winners while Toulouse and Amiens were relegated with immediate effect.
In an interview with BBC World Service Sport's John Bennett, Aulas said: "All that was needed was to stop temporarily, assess the situation and make a decision on whether to stop later on.
"It is a massive error, firstly because the country needs football and at the moment, to watch football, we are now obliged to turn to football in other countries.
"Above all, we're going to go through a dramatic period for French football that will be deprived of its revenue."
On the league's top players deciding to move on elsewhere
Aulas insists that clubs like PSG, Marseille, Lyon and Bordeaux will suffer financial blows mostly in revenue from ticketing, sponsorship and television, estimating a total loss of between 300m euros and 400m euros.
"It will be harder than before because Lyon is a club that historically is well run with its own funds," said Aulas, whose club were seventh when the league ended.
"[We have had] reserves and had this profitability which allowed us to be able to either sell well when we wanted to - being in charge of the game - or being able to keep the players because there was no need to sell."
Lyon are still in the Round of 16 of the Champions League, with a 1-0 lead over Juventus from the first leg, but if they fail to progress further in the competitions; they find themselves losing approximately 70m euros (£63m) for next season.
"It is very frustrating because also if we don't get into the Champions League - and we are always in Europe, 23 consecutive years with six or seven quarter-finals - the attractiveness of the club will be undermined," Aulas further added.
"In August, we are going to meet teams in these competitions who have been able to prepare better than us."
