Karim Coulibaly, currently with Bremen, is the latest name linked with a potential switch to Frankfurt in multiple papers and online sources. The defender could become a key signing should the move materialise, as the club seeks to strengthen in a key area of the pitch. Talks are underway, and with no competition emerging, Frankfurt are seen as the sole contenders for the player's signature. So far in this season, Frankfurt are conceding 1.9 goals a game (19 in 10), more than they'd like compared to the Bundesliga standard. The hope is Karim Coulibaly adds a bit of steel and helps make them tougher to break down. Frankfurt have recently been linked with Kaishu Sano while Bremen have had no rumoured targets.
