How is it revisionism when he said it live right there at the time? You think he was talking about the effect of the injury pile up and not taking that into account but he didn't say that. That's purely your assumption, it's more likely he was including the likes of Kulu in his original 10,11,12 players comment.
For it to really be revisionism he would have had to have had this transfer summer as it has been and then justified the massive changes and player churn with a statement and about how many players actually matched his requirements.
For me, that part of the interview was when he spoke about his players who had just achieved 11 points form 7 games and that was enough to stay up. He then went to the "10, 11 or 12" comment straight after. So I'm not sure how he could have spoken about any player's ability or mentality that he hadn't had chance to work with yet. That seemed to be the big debate at the time.
It also makes sense if you look at it numerically.
Kinsky, Austin, Porro, Davies, VDV, Udogie, Bents, Gray, Bergval, Gallagher, Maddison, Simons, Tel, Kudus, Kulu, Odobert, Solanke, Richi have all remained at the club. That's 18 and RDZ has spoken highly of some that have left implying they were good enough as well e.g. Spence. Thinking back, RDZ clearly didn't have access to some of these guys through injuries and still doesn't in a couple of cases. He has still spoken highly of guys like Simons though.
So our manager's 10,11,12 numbers just don't stack up unless you factor in the injuries.
