I may say I'm kind of qualified to a serious opinion. I saw Ajax play quite a bit under de Boer, and while getting results his tactics are always and that means pretty much always based on possession and control. His record in European football with Ajax was poor, partly because of this.
To watch, the build up from defense would quite regularly be so slow and tedious that it was simply very often extremely poor to watch. A plus might be that he definitely thinks utilizing wingers is the way to go That would be the only main point we have in our squad that I can see suits him. Other then that, lets face it, we are not a possession based, control football playing team and to think we can convert to that short term seems very ambitious to me.
He went to Inter, and stuck to his philosophy. Pretty much like van Gaal at Man United. Now that is something that scares me , as there is no doubt that unless he would adapt to both the Palace culture and develop an understanding of the English game and what fans want he will be a failure. The comments here that he would be great for the youth set up lack all substance, as traditionally that is a strong pont of Dutch clubs and Ajax in particular. Him bringing through youth at Ajax had far more to do with the available quality and set up then with Frank himself.

Other then that, he is a likable guy, mad about the game and often misunderstood for a grumpy person as he naturally has a big frown.

I drove through a town on the east coast yesterday called Woy Woy, during which an eagle flew above. Sorry lads, there's an omen if I ever saw one.

Yes it looks very impressive on paper but Ajax are in the top two in the dutch league which is a lots easier than our PL and the resources and spend power he would have had would be at the top end of the league and therefore how would he perform on shoestring budget with a lot of very average limited ability players and a chairman who is very much hands on, which top manager would not like?
