SureI mean it's a lazy analysis really and nothing to suggest it, he's Prem ready, he's played at a high level in the CL for 3 years.
He has been inconsistent (last season) but even for West Ham he was never as inconsistent or disinterested as Ndombele was, Ndombele only completed something like 12 90 matches with us for example, then got shipped around Europe for 3 years because he couldn't find a home.
