Literally everything.
His argument is that Sterling seems good value because paying 46m for De Bruyne is crazy.
He thinks it is crazy because mourinho sold him 18 months ago, after playing less than 3 games in the premier league, therefore he's not worth a big fee.
If every club followed that logic then there would be no foreign players in the league. The idea you have to be proven in the league to be worth money is laughable.
Not to mention the sycophantic arse licking of Mourinho - acting like he has other worldly judgement of players that our set up could only dream of having and is incapable of making mistakes - even though they've made half a dozen mistakes since he rejoined them 2 years ago.
It also leaves out the fact Mourinho would have more than happily kept him, but didn't because De Briyne wanted to leave. He wanted to leave because he wanted to play every week and not be stuck behind Willian.
Secondly, I'd actually argue that signing the assist leader in Europe last year, who beat Robben, Ribery, Muller, Reus, lewandowski to German POTY for only 2m more than Sterling shows how much we overplayed for sterling based on his future potential so his fundamental premise is wrong.
Sterlings fee was 50% current ability, 50% potential. De Bruyne is delivering already at the level that makes him worth £46m.
I could not have written a more incorrect, stupid and baseless article if I had tried.
