Ndombele was just poor scouting combined with changing the managers to ones who have no need for that type of player even if he didn’t get lazy. Our scouting and general decision making needs to be far better and I am a little more hopeful with Paratici/Lange/Vanai structure we will be better placed when we do spend big to make better choices. We can’t live in the shadow of the Hitchen era, that’s gone thankfully.
Ndombele is an extreme example of a bad purchase.
A more typical issue is Bissouma - looked very promising/effective at Brighton and a relative 'bargain' at £25m/£30m ish. But inconsistent with probably more 3/10's than 8/10's (although good showing in EL final) ..... we need to move him on and we may or may not get our money back, but what is certain is more consistent better players could have been bought for similar money.
But that's not untypical - probably 50% of all transfers do not live up to pre transfer expectations. And even the best DoF will find that not every player will live up to expectations..... which is where people come back to 'overpaying' for a couple of players might be done but its a risk as sometimes it doesn't work out. Do it a few times, cross your fingers and we may well be fine. Do it all the times, and we are bound to be found out - its the law of averages in play that some transfers will fail despite best intentions
