Everything you say is true, IW, but playing devils advocate, Jude Bellingham played 41 times for Birmingham City, scoring 4 goals, before they sold him to Borussia Dortmund for an undisclosed fee rumoured to be around £25M!
He was 17 years old! Same age as Esse is now!
Birmingham took the approach to throw him in at the deep end, and it obviously worked as he ended up playing 41 games for them before he was sold!
When supporters hear things like that, it’s only natural to think that their player (in this case Esse for us), could do the same! As to whether Esse could start every game next season, the only way to find out would be to play him at the start of each game and see how he does!
