I could, in a way, agree with him being a bit inconsistent. That's a young defender right there. De Ligt is inconsistent as well.
We're not getting a world class finished product and people should realise that. If we'll replace De Ligt with Milenkovic + Gabriel/Badiashile/Bremer we're not even downgrading imo and we're a man up.
Koulibaly for instance, is signing a 5 year contract for 10m/season. He's 31... That is an investment we just can not make.
