The disciplinary board determined that the spying operations were a coordinated effort by Southampton to secure an unfair advantage during the high-stakes English football tournament.
"The commission unanimously concluded that the conduct in question represented a deliberate and organised attempt to obtain a competitive advantage in breach of fundamental principles of sporting integrity and good faith," Winnie stated.
He highlighted the importance of maintaining public trust among fans, players, and clubs regarding fair competition.
"Football depends upon public trust.
Supporters, clubs, players and stakeholders must have confidence that competitions are conducted on a level playing field," Winnie noted.
The decision targets repeated regulatory infractions occurring within a financially significant tournament, according to the panel's findings.
"This outcome reflects the seriousness with which the commission viewed repeated breaches of the regulations, particularly within the context of one of the most financially and competitively significant competitions in English football.
The message is clear: cheating, in any form, has no place in the game and will not be tolerated," Winnie warned.
Winnie concluded by stating that the harsh penalty was required to safeguard the future credibility of the sport.
"Whilst the sanctions imposed are severe, the commission considered them necessary, proportionate and essential to protect the integrity and credibility of English football moving forward," Winnie said.
