Cambridge United chairman Lee Power has slammed the outcome of a transfer tribunal which ordered Coventry City to pay £40,000 for striker Robbie Simpson.
The fee could rise to £130,000 based on appearances, but Power was unhappy with the deal which gives the U's only a 5% sell-on clause.
"I've never heard of such a low figure and we're just flabbergasted," Power told his club's website.
"The up-front payment and sell-on clause is nothing short of disgraceful.
Simpson, 22, scored 17 goals for Cambridge in last season's Conference but rejected the offer of a new deal to join the Sky Blues.
Power added: "You see players moving in the Premiership for millions and still getting a 15-20% sell-on.
"This is a shambles and if this is the way forward in football then football at lower levels is doomed."
