Forgot about Sana. Lukoki and Ebecilio suck imo. Lukoki shows no indication of any football intelligence: he's all about pace. Sulejmani is decent though. But if Sana's quality, you're right, then you wouldn't need a right winger, even with Özbiliz leaving. Not that you'll miss Özbiliz, he was just another average youth prospect.
Call me negative, but I feel like most of Ajax's youth prospects in the De Boer era have been average, or at least the self-educated ones. They tend the be a bit overhyped imo. Only the scouted ones who aren't really from Ajax's youth system - Eriksen, and maybe Fischer - seem to be real assets. Only Van Rhijn seems to be a potentially good player. Van der Wiel's breakthrough was years ago, so I don't count him. But Blind, Koppers, Özbiliz, Ebecilio, Lukoki, Klaassen, etc. don't seem to be world beaters. I can't judge Dijks yet, although he did a decent job against Narsingh in the JCS. But then again, the youth system is still being reformed, so maybe that'll change in the years to come.
Apparently, Ajax and Heerenveen are now negotiating about Assaidi. Again, he's a class player, and AFCA is probably right about the fact that you'd need a left winger rather than a right winger. So it's strange that VI and other sources keep quoting Ajax insiders about their hunt for a right winger instead of a left winger. Then again, Assaidi is a left winger, so they probably realize it themselves now.
Ajax really need some more depth up front (wingers and strikers), so I'm amazed they waited so long to sign anyone. They should be able to buy quality players after their 2 consecutive championships, with the CL-money. And the sooner you sign a player, the more time he has to adapt to the team. Pre-season is the best time to sign your players, and they don't seem to realize that. But the media will without a doubt brand Ajax's transfer market apathy 'New Realism'. Amazing, how top teams only seem to be doing things wrong in hindsight, according to the media.
