A website for AS Monaco supporters has urged fans of the club to demand a refund for season tickets after superstars Radamel Falcao and James Rodriguez left the club this summer.
The two Colombians, bought last summer for more than £80million, featured heavily in the club's marketing campaign but have now left the club.
Rodriguez was sold to Real Madrid for £63m after a brilliant World Cup, while Falcao joined Manchester United on a season-long loan - the striker ended up playing just 22 matches for the club.
Last season 13 new players arrived at a cost of £115m as the small club tried to compete with Paris Saint-Germain for the Ligue 1 title.
After finishing second the club's owners appear to have lost interest with just three players arriving this summer and the £11m signing of Aymen Abdennour the only fee paid.
"Supporters, demand a refund for your season ticket," read the headline of a blog post on the Planete ASM website.
"With these two departures and with almost no new signings during the whole transfer window, Monaco fans are swinging between anger, confusion and frustration.
"The fans feel betrayed today – for having believed the club's promises and having accepted a significant increase in season ticket prices at Stade Louis II."
"There's nothing to indicate the club will accept these demands, but at least they will show our general unhappiness."
