To be fair, it’s very possible and plausible, and a high conversion rate (especially from a very small sample of shots) doesn’t mean a player has amazing shooting technique. Firstly, many goals in football don’t really even require amazing shooting technique, and also - you miss all of the shots you don’t take. There are situations where a lethal shooter, like Kevin de Bruyne for example, would shoot where others wouldn’t. A ball dropping from the sky at the edge of the box represents a different prospect to KDB than it does for Hojlund. The same ball might be brought down and laid off by Rasmus because the shot is ‘not on’.
Van Persie had the best shooting ability I can think of at United, and it has little to do with a conversion rate. He could simply strike the ball sweetly, accurately and powerfully from a range of situations. He can drive them, bend them, drive/bend at the same time, place them with accuracy. I don’t think Hijlund has displayed this yet. He has a good conversation rate, but in almost two seasons, he still has a fair bit fewer goals than Persie managed in his first season alone. I say this to say, it’s an incredibly small sample.
