It's fascinating that the much-maligned (albeit popular) Lustig factors better than Tierney on this comparison, although I appreciate there is more than this to being a full back. I'm not a great fan of Ntcham and wonder at times if what he brings is outweighed by what he doesn't but I'm prepared to be persuaded otherwise based on this. I think it shows that there is an aspect of "chaos" to football that prevents even the excellent and useful analysis of CBN from being absolutely conclusive (and I'm sure they'd never claim it is) but also means that the evidence of your own eyes (as in my own opinion of Ntcham's contribution, which I'm now reconsidering) can easily be well off the mark. If you'd asked me prior to seeing this who would score best, I would have said either McGregor or Rogic.
