The Germany international has joined Hoffenheim from SV Darmstadt 98 for a fee in the region of 2.8 million euros in July 2016. The 29-year-old has a valid contract with Hoffenheim until June 2019.
Since his arrival from SV Darmstadt 98, Sandro Wagner has scored 12 goals and provided four assists in 32 games for Hoffenheim in all competitions this season.
Sandro Wagner has represented Germany at Under-21 level, winning eight caps and scoring four goals.
The Germany international is thought to perfectly fit the profile of attacking player Paul Clement wants to target in the summer transfer window.
Sandro Wagner is a player who has impressed many European clubs in the last season, and it is understood that Swansea manager Paul Clement would prefer playing him as a forward.
Euro Football Rumours understood that Hoffenheim representatives could look to offload Wagner if a sufficient offer comes for him.
Premier League club West Ham are apparently trailing Swansea in the pursuit of Hoffenheim striker.
How strong that interest is and whether Swansea will make a summer move remains to be seen but it is certainly one worth keeping an eye on.
