Since our defense has been such a topic of conversation at the Euros, I figured I'd talk about our biggest "hoffnungsträger" in defense. For this, I'm focusing on kids who haven't yet established themselves at the senior level, so I won't be discussing Uduokhai, Schlotterbeck, or Torunarigha...though his injuries have prevented him from fully establishing himself at the senior level.
And the best place to start is with the literally biggest of the lot;
Armel Bella Kotchap ('01). The Paris-born Bella Kotchap has been starting for Bochum...44 BuLi2 matches under his belt already & he won't turn 20 until december...and was crucial to their securing 1st division football for next season. The absolutely massive kid has excellent mobility / quickness to go with his power / balance / length. Capable of making some truly great tackles / interceptions and a force in the air, the kid has also shown he can deliver some really high caliber passes...both long aerial balls and ones sprayed out to the wings along the pitch. This coming season will be a major test for the young Bella Kotchap, but if he passes it well, he should be poised for a big move next summer.
The next kid I wanna talk about is
Bright Arrey-Mbi ('03). Like Musiala, Bayern snagged him from Chelsea's academy & he has played for an English youth NT before...8 matches with their u15s before switching to our u16s. Unlike the others I am discussing Arrey-Mbi has almost no senior team experience. With his only PT for Bayern's 1st team coming in the CL against Atletico Madrid; when Arrey-Mbi started at LWB in their group-stage 1-1 draw...other than that & 1 match with the u19s, his season was spent entirely with Bayern II in the 3rd division where he was an important starter. Not as big or powerful as Kotchap, Arrey-Mbi is quicker and seems to have genuinely special instincts/understanding of the game. He's probably my favorite to become our next Hummels.
Marton Dardai ('02) is probably the biggest name of the lot. Famous father, been on the scene for a long time, plays at a high visibility club, and has started breaking in at the senior level; with ~15 matches for Hertha to finish out the season. Dardai has sufficient size (1.88m) and good defensive instincts...but I wonder if he'll get pushed further forward at the senior level to make use of his skill on the ball. We'll see if he has the class of a Kimmich or Kroos if he does end up at the 6, but he's impressed me on the ball; both in those deeper areas as well as pushing forward. If he does stick in defense, those ball skills could be fantastic as LCB in a back 3.
The last teenager I wanted to bring up was
Malick Thiaw ('01). The young Schalke defender is eligible for Finland and I'm not sure if he's more Kehrer or Klostermann, but he's another very interesting teen. Excellent mobility and some impressively timed challenges in the box for Schalke's senior team, have put him clearly in the picture for the NT if he continues developing well...getting a nomination to the u21 team despite the s***show around him. Schalke was such a mess that it's hard to assess his game, especially in build-up play, but he has certainly showed the flashes of an interesting defender.
Honorable mention:
Lars Mai ('00), no longer a teenager Mai has become a regular starter in the 2nd division for Darmstadt and is one of the most elegant german defenders I have seen at the youth level. Not sure what the future holds for him, but his ability to read the game at a high level despite his age keeps me intrigued to watch him develop further.
Other interesting kids include:
Antonis Aidonis ('01),
Arbnor Aliu ('03) & maybe
Frederik Jäkel ('01)...though personally, I haven't been too impressed with Jäkel whenever I've seen him play for our youth NTs :-/
