Barcelona have been fined €300 by the Royal Spanish football federation for their actions in the signing of Atletico Madrid forward Antione Griezmann.
Atletico claims that Barcelona reached an agreement to sign the Frenchman when his release clause stood at €200m (£178m/$221m).
Griezmann ended up completing a €120 million (£107m/$134m) move to Camp Nou on July 12, with his buy-out clause reduced at the start of the same month.
Barca have been sanctioned by the Royal Spanish football federation on Thursday, with the club now due to pay a €300 fine for a breach of rules.
It had been suggested that the Spanish champions may be forced to pay a fixture behind closed doors, but no ban on supporters has been issued.
The RFEF have released an official statement, which reads: "It is evident that the amount of economic sanction does not bear any proportion to the importance of the facts that have given rise to this file.
"Taking into account the economic capacity of the club and the amount of the economic operation that has given rise to this file, this Committee is aware that the payment of 300 euros, beyond its merely symbolic nature (the fine is imposed because the issued club has been considered the author of a disciplinary infraction), will not contribute to the sanctioned club in particular and, probably, other clubs that may be in the same situation in the future, adapt their behaviour to what is required by regulation.
"However, this is not a sufficient reason for this Committee to opt for the imposition of a sanction - the closing of the stadium by a party - which, as Mr Instructor states, seems to be intended for infractions of another nature."
Atletico have ultimately missed out on the €80 million ($87m, £71) they feel they are owed, but club boss Diego Simeone will likely be unaffected by the news.
Spanish publication El Mundo lifted the lid on Barca's alleged wrong-doings, claiming they had access to emails which proved that the club finalised an agreement with Griezmann back in March.
The 28-year-old has settled in quickly at Camp Nou, netting three goals in his first six La Liga appearances.
Greizmann will likely retain his place in Ernesto Valverde's line up for a trip to Getafe on Saturday, before Barca prepare for a Champions League clash against Inter Milan four days later.
