Hoppe at under 5M is a steal. You will not lose money on the guy. Worst case scenario he's a complete bust (which I don't see happening with his size, athleticism, and technically ability) and he gets sold back to MLS for what you paid for him. At 20 years old he's made enough impact with the USMNT already to be worth that to domestic clubs over here in the States.
Hopefully he'll be an instant impact sub who will dribble at defenders and is a presence in the box at 6-3. He's very much a late bloomer by today's standards, he was a top goal scorer in our national development league but was never called into the youth national team for some reason, which isn't surprising considering how woefully managed our youth team shave been over the last 4-5 years. He signed with Schalke when he was 18 without much fanfare, and then came out of nowhere to be their top goal scorer playing only half of their matches last season after starting the year in the U20's.
From watching Schalke and seeing his goals I assumed he was a fox-in-the-box poacher type, because that's what they asked him to do, but this summer with the Gold Cup showed us a completely different side of his game. He's highly aggressive, will run and press for 120 minutes; he will dribble at any defender from the wing or inside forward position, and his goal to beat Qatar in the semifinals came from crashing the back post and jumping over a defender after running non-stop for 85 minutes.
He actually has a lot of Richarlison in him, and selfishly as an American I would love for him to be Richy's understudy. I'm not saying he will be on Richarlison's level, but his style of play mirrors a lot of what our favorite Brazilian does. High work rate, flair on the ball and an understanding of how to finish in the box.
