19 year old top players, are normally shining bright in the teams they play for.
Michael Owen was a top player at 17 made England's World Cup squad at age of 18 in 98. Owen was Liverpool's leading goalscorer every season from age 17 thru to age 25 (1997 to 2004 seasons).
I've seen diddly squat from Elliott to say he's going to be a top player for Liverpool.
Indeed, not only Owen, but Gerrard or even Foden and Haaland more recently. That said, not all players are the same, Salah was probably as Eliott at the same age, lots of promise but was moved from Chelsea (he was probably older). I don't understand why Klopp rates Eliott that much, maybe he is very good in training
