Both natives of Western Australia, the key-position duo will be highly sought after next year should they remain unsigned for the 2025 season.
English was said to be of high interest to WA clubs before signing a two-year extension last year, with West Coast anticipated to come calling again in the near future as they look to plan their ruck stocks for the future.
Fremantle could express some level of interest in English given Sean Darcy's current deal will also expire at the end of next season, with the Dockers set to make a call on whether they look to move Luke Jackson into the first-string ruck role on continue to utilise a star partnership to share the workload.
Unlike English, Naughton won't be eligible to exercise his rights as a free agent in 2024 - a season which will be the high-flying forward's sixth season at the Kennel.
The Peel Thunder product is expected to be on the radar of both WA sides, with the Eagles and Dockers likely needing more firepower by the 2024 off-season.
According to News Corp, both Fremantle and West Coast won't be alone in tracking the services of Naughton and English, with as many as eight clubs said to already be showing some level of interest in their services.
Both clients of Corporate Sports Australia, discussions with English and Naughton on their future aren't set to be held until the end of the current season, with the pair seen to be satisfied with life at the Bulldogs.
West Coast will likely factor English's age and experience in their pursuit, with the Dogs ruckman to be 27 come the 2024 free agency and trade window and likely a more mature option for the club to consider as they work through the early years of their list rebuild.
Anticipated to hold an early draft selection this year, the Lathlain-based club could look toward WA prospect Mitch Edwards with a first-round pick. The 207cm South Mandurah product could suit the club's rebuild as a cheaper investment over English.
The Eagles also added South Australian Harry Barnett to their ruck department last year with their opening selection of the second round in the National Draft.
