Notably; the Saudi's aren't paying excessively big fees; mostly big wages........
I'd be suprised if we could get anything above 30m for him; some thing I think it no less likely to get from an EPL team (the OG 60m only ever came to pass cos it was between two EPL clubs.... The only clubs in Europe that can afford 60m player shop from the top shelf)...... Said in the summer; I could see him getting a move to somewhere like CP or Fulham if things didn't pan out here (esp. the latter considering their Mitro sale).
He'll likely still prove useful over the remainder or the season if he stays fit (dreadful timing that he now makes it 3 LWers we have on the sick-list); but if a bid comes in and we have a successor in the pipeline I think it would be wise to act.
Your homework is lacking, mate.
Neymar for 90 mil
MALCOM for 60 mil (!!) YES, that Malcom. 2 caps for Brazil, same age as Richie brought from Russian league.
OTAVIO for 60 mil (!!) - I don't know who is is and 90% here have not heard about him either, I bet.
May I note, that all those 3 are ... Brazilian attacking players?
While Neymar is a brand, they also paid 120 mil combined for two nothing-players.
But let's keep going.
Mitrovic for 53 mil - in no way is Mitrovic more of a high-profile player than Richie
Fabinho for 47 mil - DM that is 29... not as gross overpayment but still, no one in Europe would have taken him for that
Mane for 30 mil - year earlier left for same money from Liverpool due to short contract. got year older, flopped badly in Bayern and had long contact (which usually means higher value)
Jota for 29 mil - lad has highest market value in his career of 13 mil (!)
So this quick Google-job resulted in ... 6 players grossly overpaid for, even if we leave out Neymar where there could be some debate due to his "brand".
Two of them are totally unknown Brazilian forwards that have nothing to show for compared to Richie.
Three are Brazilians.
So... yes... the are paying excessive fees.
