Lavia is only 19 though, I know Onana is only 21 but at 19 he has a year in the PL and looked very good. Clearly the professional scouts working for RS and Liverpool (who I would suspect are better at judging a player's ability than you or I) think Lavia is the player to go for, otherwise the bids would be for Onana
With all due respect mate, that's pure Alehouse logic. Listen to yourself, trying to construct an argument about age and time spent in tbe prem and which clubs are Interested in which player and being all Paul Merson about it.
Lavia plays for a team that's been relegated, and so is 'in play' right now. Onana doesn't, and has 3 years left on his contract, and so is not 'in play'.
The value of either player only comes to light when they're in play, and this why we know what Lavia might be worth.
No-one's made any bid for Onana, so your guesswork about what he's worth is basically that - an amateur guess.
In the circumstances, with 3 years left and a year in the prem and a young Belgian international, Everton would be crazy to consider anything less than Lavia + 50%, and then see who makes a bid.
IMHO.
