My own personal opinion is that 18/19 is way to early to judge a player. So these 40/50m purchases IMO aren't the answer to creating a 'future dream team'.
23/24 is a much better age to sign these youngsters for me. That's the age i would prefer we focused on.
Sorry, but that's an absolutely ridiculous thing to say.
Tielemans has played 4 full seasons of football. He's played 3 seasons in the Champions League. If 180 professional games isn't enough for the world's best coaches and scouts to figure out he's good enough than the game is gone. If nothing else the fact Monaco are desperate to sign him should tell you everything you need to know when half of Europe wants to buy their starting XI.
You look at Gabriel Jesus and you know immediately that he's good enough.
Anyway you're going to be disappointed, Pep's made it incredibly clear that he likes working with very young players and he's become the most successful coach in the world by doing that, he's not going to change any time soon, he'll always like buying young even if he brings in a couple of mid twenties players.
