Rangers have wrapped up the signing of Derek Cornelius, who joins from Marseille. The defender's move has been made official after successful negotiations, a passed medical, and contract signing. The confirmation has been welcomed by fans, who've waited eagerly for this long-anticipated deal to go through. Derek Cornelius had attracted interest from Cremonese, but it was Rangers who secured the agreement and completed every step of the process. A deal that once seemed uncertain is now fully confirmed. Rangers's back line has been a real strength this season, conceding just 1.0 goals per game (6 in 6). Derek Cornelius would be expected to slot into that unit and hold his own in an already solid setup. Marseille continue to be linked with Lutsharel Geertruida, Kobbie Mainoo and Hamed Junior Traore while Rangers are also rumoured to be tracking Jesuran Rak-Sakyi and Bojan Miovski.
