Isn't Plettenberg Tier 3? He has inside sources at Bayern but nothing elsewhere. Bayern have Colwill as a target if they don't get Tah, however I'd imagine the conversation Bayern reps and Clearlake have over the availability of Colwill will last fewer than 3 seconds.
I'm more worried about where Nkunku and Palmer fit into this. Neither would benefit as being a wide left sided winger, and both together in the #8 positions would be very top heavy.
