Arsenal have been fined Â£60,000 by the Football Association (FA) after the Premier League side breached the FA's football agent regulation rules.
A statement from the English football governing body on Monday afternoon stated that the Gunners have also been given a warning over their future conduct for discrepancies in relation to the transfer of English defender Calum Chambers from Southampton in July 2014.
Also, the player's agent, Alan Middleton, has been fined Â£30,000 by the FA and handed a three-month suspension from all "agency/intermediary activity" for his involvement in the transfer.
"This suspension shall be suspended in its entirety for 18 months from 23 October 2015 and will not take effect unless he commits an offence contrary to the agents regulations or The FA's regulations on working with intermediaries during this time," the statement said.
The charges against Middleton were found correct by the FA while the Gunners admitted to a part of the breach.
"Arsenal admitted part of the breach but denied another, which was found not proven following an Independent Regulatory Commission," the FA statement concluded.
Chambers moved to Arsenal for an undisclosed fee, believed to be in the region of Â£11million.
