Transfer interest is building around Arne Engels, with Leipzig understood to be weighing-up a move for the Celtic 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. Talks are underway, and with no competition emerging, Leipzig are seen as the sole contenders for the player's signature. So far this season, Leipzig are steady at both ends (1.94 goals scored per game, 1.41 goals conceded per game). The role for Arne Engels would be to keep that balance while lifting performances across the pitch. Alongside this, Celtic are said to be exploring Aurele Amenda, Joel Piroe and Callum Wilson with Leipzig likewise connected to Rocco Reitz, Radu Dragusin and Tarik Muharemovic.
