Nbombele impressed me so much against us, I couldn't believe he was only 21. Frankie I've not watched live, but watched a lot of the every touch vids (Which I like as you see mistakes too), he also looks so impressive, but his physicality worries me, and he plays in a very poor league. I think I prefer Ndombele right now, but I reckon Frenkie could well be the better player long term. Frenkie will cost 50-60% more though. Very tough call for whoever has to decide.
