Yeah, i know its "in the ballpark" for the numbers wise. jack was £105.75m for some reason, so i went with the 5%
Yep, I noticed that one too. The older the figures, the more they may have changed! De Bruyne's has changed hugely.
It's fairly standard that hacks will just take the facevalue figure from transfermarkt as their 'research', and it just inflates transfer costs.
Yeah I have 2 spreadsheets, one with the transfermarket figures and the -5% i use for reference.
It comes from conversion errors between £ and € based on the way they’ve organised their websites. The main one is German so it’s based on €
De Bruyne cost £54m which was €75m in 2015 so it goes inhe database as €75m.
When you visit their UK site now, it converts from €75m to £ based on todays conversion rate which makes it £68.4m
If the £ got stronger against the euro than it was back in 2015, the prices would start being lower than they actually were.
