Tesche was a regular under Stuart Pearce at Forest, but fell out of favour under Dougie Freedman and was allowed to go out on loan to Birmingham.
A permanent move would make sense, with a recent poll in the Birmingham Mail showing 77 per cent of fans wanted him to be the club's first priority this summer.
The German was a free agent signing from Hamburg last summer, and selling him on for a profit would be good business if he is not in Dougie Freedman's plans.
Who should Forest replace Tesche with?
Forest's options are limited due to a transfer embargo, but a strong candidate should be former Leeds United midfielder Rudolph Austin, who is a free agent, despite the recommendations of Neil Redfearn to keep him at the club beyond the summer.
Austin is a former Leeds captain and is the experienced figure Forest need in midfield to complement the emerging talents of Ben Osborn and attacking instincts of Henri Lansbury.
A return of injury stricken captain Chris Cohen would be welcome, but Forest have learned by now they cannot assume he will stay healthy, and picking up a Championship hardened player like Austin, 30, would be a smart free transfer.
|Team||Won Tackles per game||Interceptions per game||Passing Accuracy||Key Passes per game||Appearances|
|Robert Tesche||Birmingham / Forest||2.32||1.88||79%||1.03||34|
Tesche narrowly edges Austin in three areas, but the pair recorded very similar statistics with their performances across 2014/15.
If they are to cash in on Tesche then Austin could fill his role adeptly, and play a key role for Forest across the course of a 46-game Championship season as they aim to push for promotion.
