This manager has some kind of magic touch. Simon Jordan calls it "alchemy", and he's right in the sense that the absolute elite, winning managers have something that the also rans that may be very good do not, and it's hard to quantify exactly what it is. They seem to rearrange the pieces around them in the precise way, sometimes the only possible way that average managers would miss.
The vast majority of decisions he makes in game work, his decisions off the pitch definitely have worked, and suddenly a bunch of misfits look like a team. He's only done it at Ajax, perhaps, but so far in his career he is a winner with no evidence to the contrary and the early signs couldn't be much stronger.
If we keep improving this squad there are good chances with this guy in charge.
