That final paragraph is another reason why the Leipzig move makes sense. They also have a strong tactical system and give youth a chance (well, young up-and-coming players, anyway; I don't know about their own youth).
It's an interesting conundrum Ajax are finding themselves with. To be more competitive internationally, you guys have loosened the purse strings, so you can keep players longer and buy higher-profile players, like Haller. But that creates a risk for your development model, as those players are in the way of the youngsters that otherwise would have had more opportunities to play in those positions. There was a piece in the Volkskrant some weeks ago that this has been an issue recently (I don't remember details), and as I've been saying, I suppose it's one of the reasons behind Brobbey's move. It's something you guys will have to figure out.
I don't actually know that one. I'm finding 'it fits as a flag on a broomstick' online, but I feel it rather misses the 'modderschuit' (mud barge).
