Leyton Orient are lining up a move for defender Michael Raynes from League Two rivals Carlisle United, HITC Sport understands from sources close to the club.
Orient manager Andy Hessenthaler has been busy in the transfer market so far this summer as he looks to reshape his squad and he has identified Raynes as one of his top targets.
Raynes is regarded as one of the best central defenders in the lower leagues after making over 300 appearances in his career to date.

The 28-year-old began his career at Stockport County before moving on to have spells at Scunthorpe, Rotherham, Oxford, Mansfield and now Carlisle.
Raynes joined Carlisle last summer on a free transfer and he has gone on to establish himself as a key player for Keith Curle's side.

The tough-tackling defender was a virtual ever-present for Carlisle last season, making 49 appearances in all competitions and scoring three goals for the Cumbrians.
Orient are now hoping to lure Raynes away from Carlisle as they look to build a side capable of challenging for promotion, but Carlisle are reluctant to lose their star defender to one of their League Two rivals.
