Fremantle have re-joined the chase for Geelong midfielder Tim Kelly, less than six months after Kelly refused to join the Dockers during the Trade Period.

After Kelly's first season in Geelong - in which he came second in the club's best and fairest - the 24-year-old was interested in a move back home to WA, with Kelly, his wife and three children struggling to adapt to life so far away from their family.

Kelly and his player manager, Anthony Van Der Wielen, would only deal with West Coast, with the two parties unable to agree on a suitable trade.

However, AFL.com.au now understand Kelly's camp are keeping tabs on the Dockers this season, and namely the impact new football boss Peter Bell has on the club.

Bell could be the leading factor that would swing Kelly's decision to the Dockers, while Fremantle also have more salary cap room to accomodate Kelly in 2020.

Despite the Cats keen to keep the impressive midfielder, it is believed Geelong still loom as Kelly's third and last preferred option.

West Coast still remain as Kelly's favoured destination, given the Eagles' long-time interest in the WA product, which dates back to 2016.
