FantasticMrFox -- Yildiz is a classic example of looks a player, but more so in minutes (or matches) rather than seasons.
He's got everything you want from a wide forward or attacking midfielder in that he's got a big frame, can ride challenges and compete physically, but he's also tricky enough to create openings. He has a solid shot and can also create for others.
But, he's inconsistent and there's still questions about what his ceiling looks like. I actually think a young RVP is a decent comparison. You'll notice there talent immediately but they haven't refined their game (like someone like Saka) to have a consistent impact.
