Collingwood midfielder Josh Thomas, has put together a promising start to his 2018 campaign thus far.

Yet, while he is enjoying a career-best this year, the worrying sign for Collingwood is he is yet to resign beyond this year, with rival clubs circling his contract status each week.

He was again among Collingwood's best against the Lions, collecting 22 disposals and kicking three majors, to help propel his team to a great away win.

He joined the Pies in 2009 through the NAB AFL Draft, and has already kicked the most goals in a season in the seven games this year, after an injury and suspension-riddled beginning to his career.

He was an unrestricted free agent last year, however signed a one-year deal. However, with the mid-year point coming up, Thomas has yet to open discussions about a new deal with the club.

Thomas, along with now-Giant, Lachlan Keefe, were involved in a doping scandal back in 2015, and both served two-year WADA suspensions.

He, along with Jordan De Goey, are two key players that the Pies will want to hold as they attempt to return to September action.

AFL.com.au reported last month that interest was rising for the latter, including St. Kilda. De Goey, although having a troubled past, has been a revelation since coming back from a club-imposed suspension.
