The Hammers are likely to let Alex Song leave the club without a permanent deal once his loan stay from Barcelona ends this summer, meaning West Ham will be looking for another defensive midfielder.
Now, The Mirror believe that West Ham are targeting Bayer Leverkusen's utility man Reinartz as a possible replacement for the former Arsenal star.
Reinartz, 26, is a strong, physically imposing player who can play in defensive midfield or at centre back, making his name with Leverkusen having come up through the ranks with the club.
After 16 years with Leverkusen, Reinartz - who has earned three caps for the German national team - could be on his way out of the club.
Reinartz's contract ends this summer, meaning he will be available on a free transfer, unless Leverkusen can convince him to stay ahead of the summer transfer window.
Landing a replacement for Song without paying a transfer fee would be ideal for West Ham, so it's little surprise to see that Reinartz is now being linked with a move to Upton Park, with the Germain certainly fitting into the Hammers' budget this summer.
