Hey guys, I'll try to give some info about this Dutch team
Klaas Jan Huntelaar (striker, Heerenveen, no9) will be the main man to watch for your guys, as hes got a very good technique and fightingspirit on the pitch. He's also done well recently so he's in form. His feeder from the left will be Feyenoord's Castelen (the no. 10 on the pic). This guys got pace and can be brilliant but is not a constistent good player. He'll be hard to catch for your defenders though. His replacement can be OWusu Abeyie from Arsenal, strong and fast guy as well but lacks discipline and has funny sometimes useless movements in his body. On the right we'll most likely see the guy pictured on your tickets, Celta de Vigo's Daniel de Ridder. He's an Ajax product so schooled to play on the wings. De Haan may prefer Feyenoord's Vincken to play on the right, cause that guy also played there during the U20 WC. I really couldnt tell you which one of them is better, I think I'll give the edge to Vincken as he's faster. Neither is worldclass ala Robben or Van Persie.
Rasta man Emanuelson wont play in the mid as he's transferred to the big Oranje, same goes for other youngsters such as Maduro Vlaar and Babel (all of those guys did play in the WC U20 last year so its a plus for you that they dont play). You wont have to worry about a van Persie or Robben either. Other good players that deserve to be mentioned are Zuiverloon (no. 8) from Feyenoord but now loaned to RKC where he's doing well, he is good defender, or defensive mid. Drost, from Heerenveen (not on the pic) is another good player, he's wanted by PSV BTW, AZ's De Zeeuw (no.3) and Utrechts Tiendalli (no.2) are decent players too from what i've seen, Tiendalli is a regular in Utrechts team so he's got rhythm. Keeper Boy Waterman (heerenveen) is ok but still very young and not 100% reliable. He's got footskills though which is a plus... dont know if Vermeer was selected as well but IMO he should have been as he was ok during the junior WC.
Dont know what you think of this list but IMO its a good squad. The team is known for losing to minors though, or better put not known for super results so anything's possible, dont put yourselves in the underdog position.
You'll play the away match in Heerenveen as Walter stated, you may have noticed that this U21 has some of their players but it is also the home of Foppe de Haan, the coach. A perfect stadium for a match like this and the fact that its sold out means our guys will have great support. You need to beat them in Slovenia, which IS possible, and then you'll definitely have the chance to beat the Oranges at their home.
