Both the Blues winger and defender sought moves on deadline day but ultimately remained with the club’s so-called ‘Bomb Squad.’
The PFA is now understood to have stepped in to ensure the pair are being properly looked after.
According to BBC Sport, the PFA has reached out to Chelsea to ensure that Sterling and Disasi have a proper environment to train at an optimal level, despite being excluded from first-team activities.
The union has also reminded clubs of FIFA’s strict regulations regarding players who are isolated from their squads under circumstances that could be deemed ‘abusive conduct.’
In such cases, players may have the right to terminate their contracts on the grounds of ‘just cause.’
