Celtic have a lot of options at centre-back right now. But they could be reduced quite a bit this month. Nat Phillips has already returned to Liverpool, after what was a disappointing half-season loan spell at Parkhead. Yuki Kobayashi has not made a single appearance in this campaign and there is believed to be interest from Japanese sides in his signature. And Gustaf Lagerbielke could head for the exit door as well despite arriving in the summer.
If both Kobayashi and Lagerbielke did leave, then Celtic might need another centre-back. Cameron Carter-Vickers has struggled to remain fit throughout the course of the season and there are many fans still to be convinced by Liam Scales as a long-term starter.
McKenna currently plays for Nottingham Forest in the Premier League. But he has barely featured in recent times and could be on the move in the very near future. In fact, an exit would make sense for both parties.
Celtic and Rangers both want £6 million centre-back
McKenna is entering his prime at 27 years of age. He was a key part of Nottingham Forest's team not too long ago. He also has prior experience of playing in Scotland and is a Scottish international too.
Thus, if Celtic end up signing McKenna, they will be getting an experienced centre-back for sure. Exactly what this team might need following the summer exit of Carl Starfelt.
McKenna joined Nottingham Forest from Aberdeen back in 2020 for an initial fee believed to be £3 million which could rise to £6 million. It remains to be seen what kind of a figure it takes to bring him back to Scotland.
