Transfer interest is building around Grischa Promel, with Leverkusen understood to be weighing-up a move for the Hoffenheim midfielder. While there has been no official bid as yet, the club may act swiftly if they decide to pursue the deal before the transfer window slams shut. Wolfsburg, Frankfurt and Stuttgart may look to intervene if talks continue without resolution. So far this season, Leverkusen are steady at both ends (2.05 goals scored per game, 1.29 goals conceded per game). The role for Grischa Promel would be to keep that balance while lifting performances across the pitch. No fresh speculation surrounds Hoffenheim or Leverkusen regarding other transfer targets.
