What are you on about!! Iwobi on average per season at Arsenal scored 3 league goals and 3-6 assists. That's equivalent to what James did last season and Everton signed him last year for 28m plus more than 30m with adds on. What the feck Brewster did to even get 23m price tag, did nothing in EPL.
Let me tell you more, Dunk & Tarkowski have price tag of 50m or above, Fulham signed Mawson for 20m, Andre Gray cost 18.5m, Pickford 25m, even Andy Caroll was 35m years ago as well as Stones 50m. That's the reality, British or homegrown player is always overpriced.
15m is just an average transfer fees for players that signed from Championship club like Che Adams, Ben Gibson Llyod Kelly and etc which include when we signed James from Swansea. While majority the ones transferred from PL clubs cost minimum around 20m in average for young homegrown players which I have mentioned before.
What about you stop talking non-sense and start list me lot of names/cases, no point arguing and make false claim.
