Deal struck for Aissati?

Reports are coming out this morning that Ajax and PSV have actually agreed to terms on the transfer of 19 year old midfielder Ismail Aissati. I know rumours were flying around about this transfer but I really never though this would actually happen. Transfers between the big 3 in Holland have been few and far between recently (besides Perez), especially when it comes to young up and coming talents like Aissati. As exciting of a prospect as this deal may be, its getting very close to the start of the season and Marco STILL has not brought in any help for the back line and anyone that says that Aissati will be a defensive midfielder is on crack. So will this year's Ajax end up being a carbon copy of the Euro 08 Oranje squad? A beautiful attack with a questionable back line? That's a scary thought. To make things worse, it looks like Henrique, the one defender that van Basten seems to be showing a lot of interest in is very close to signing a large deal with Barca, who may then loan him out to Bayer Leverkusen.
