Sheffield United will turn to the European Commission for compensation if an independent arbitration panel fails to over-turn their relegation.
The Blades are protesting at the Premier League's failure to dock West Ham points over the signing of Carlos Tevez and Javier Mascherano.
Blade chairman Kevin McCabe believes their relegation will be overturned.
But he told BBC Radio Five Live that if the verdict goes against them he "would not say that's the end of the issue".
"I don't believe the arbitration will go against us"
McCabe added: "We have a trip to Brussels to meet the European Commissioner for culture and sport, Jan Figel, on Friday, so we are making our presentation there this week.
"We'll go to the European Commission for them to opine. We believe we have maybe got a human rights issue because of the loss of jobs that has been established if we are relegated, the salaries that are reduced because of going from the Premiership to the Championship and those sort of issues."
However McCabe accepted that: "If the arbitration were to go against us on Monday we recognise that we are relegated to the Championship.
"But I don't believe the arbitration will go against us at all.
A supporters' delegation headed to Parliament in London on Wednesday to canvas Government support for their battle.
And McCabe said: "There was an injustice committed."
McCabe is confident the club will be reinstated to the Premiership - and Professional Footballers' Association chairman Gordon Taylor also believes they have a "valid case".
An arbitration panel on 18 June will hear the Blades' claim against the Premier League's failure to dock West Ham points over the Tevez saga.
606: DEBATE
The Premier League had initially told Sheffield United, who were relegated on the last day of the season, that they were wasting their time and money.
But McCabe claims officials have since told the club they will regain their top-flight status if their claim is successful.
The issue has dragged on since March when the Hammers were charged by the Premier League with breaching rules in relation to the signings of Argentine duo Tevez and Javier Mascherano.
"I think Sheffield United have a real valid case"
Tevez and Mascherano, who has since left for Liverpool, joined the club in August.
West Ham were found guilty of acting improperly and withholding vital documentation over the duo's ownership but they escaped a points deduction and Tevez was allowed to continue playing.
He was one of the major factors in the club's late escape from the drop but the Blades have vowed to fight the Premier League's decision.
McCabe stated: "I think the Premier League accept they wish the arbitration was not happening.
"But in the knowledge it is happening and it cannot be prevented, then if the decision is overturned we should be reselected to the Premier League.
"Since we really looked into the whys and the wherefores of the Tevez affair it became apparent that a wrong decision was made."
PFA chief Taylor added: "I think they have a real valid case. I just think it's sad that this has been a shadow hanging over the season.
"You've got to give credit to West Ham for the way they battled back and to a lot of those supporters and a lot of those players. They are innocent in this.
"But there were people involved at the club who knew what they were doing and they are the ones who should be held to account."
