De Jong’s Cambuur was on track for promotion to Eredevisie, holding an 11-point lead over closest rival to the Dutch second tier.
But they will remain in the Eerste Divisie next season after the campaign was effectively declared null and void due to the coronavirus pandemic without promotion or relegation.
West Brom and Leeds United have a considerable lead over Fulham, third, in their promotion offer in the Premier League.
Slaven Bilic’s Albion are six points ahead of Scott Parker, while Leeds are one point ahead.
“We are furious,” de Jong told BBC Radio 5 Live. “It is good that they have been transparent with us, but they must be athletic. In the beginning [cancelling the leagues] was only going to affect the big clubs, and we’re a small club.
“But in England you have Leeds United, a very large club, and they are increasing, right?
” Well [if the league is cancelled] they have to go to the European Court and say, “At the top, clubs must follow UEFA rules [allowing them to play to finish the season], but we have to follow the English rules, how is that fair? ”
“It was amazing for us at the top. 75% of the matches were played and they told us that it is not clear – it is incredible. “
Having seen the non-league season already halted early, there remains uncertainty about how the Premier League and the EFL might approach the situation in the weeks and months to come, and Albion and Leeds still have nine league matches scheduled.
Gary Lineker, meanwhile, is concerned that declaring the campaign null and void may be the only answer to the long-term benefit of the sport – even if it doesn’t seem like a fair short-term decision.
