Everton and Nottingham Forest are among several Premier League clubs considering legal action against Chelsea following sanctions imposed by the league for undisclosed payments, according to reports.

Senior figures at Everton are preparing to formally explore legal options in response to the Premier League's disciplinary measures against Chelsea. The potential legal challenge relates to sanctions imposed on Chelsea over payments that were not properly disclosed to league authorities.

Nottingham Forest has also been identified as another club exploring possible legal action against Chelsea. Multiple sources indicate that several other Premier League clubs are similarly considering their options, though the specific identities of additional clubs have not been disclosed.

The potential legal challenges appear to stem from concerns about how Chelsea's undisclosed payments may have affected competitive balance or compliance with league regulations. The exact nature of the undisclosed payments and the specific sanctions imposed by the Premier League have not been detailed in available reports.

The situation highlights ongoing tensions within the Premier League regarding financial compliance and transparency among member clubs. Any formal legal proceedings would likely involve complex questions about league governance and the enforcement of financial regulations across Premier League teams.
