He will get some minutes after next summer I think, amazing talent indeed...Tremendous talent but at least 1-2 yrs away from 1st team impact IMHO

So Lamine training under Xavi at 15 was meaningless too, right? Because that was 'just pre-season' with some starters out. Oh wait — that 'meaningless' pre-season launched a superstar. Forest. Trees. Try to spot the difference
Yes, pre-season. Yes, Phase 1 of pre-season is without most of WC players but also why it matters for Tunkara. He's not going to win trophies or spot in XI but training under Flick, learning from 1st-team players, building relationships and tactics with staff while learning to become a professional athlete. This move accelerates his development so doesn't mean much
Same will apply to your boy Hamza, btw
My thought also. This dude will probably be ready to get some minutes already in the first half of the season. I know he's played mostly as CAM, but we're stacked there and Flick should play him on RW - also less pressure than playing centrally. He's alright 1v1, he's fast and has the physique/speed imo - he of course isn't a winger like Yamal was that age, but if we don't get a RW backup Tunkara should get some minutes there.Won't be surprised if he's one of those players who play better taking a step up surrounded by better players and structure.
