The actual currency which exchanged hands would have been Euros and As the transfer was between a German and an English club the Leva doesnt enter anywhere into the equation The Leverkusen page should show the amount he was sold for in Euros the Tottenham page should show the amount he was bought for in pounds the Berbatov page except on the Bulgarian language version should show the amount in Euros Leva if used at all could only really appear on a page dealing with Bulgarian footballers or famous Bulgarians in general It is also worth noting that USD and Euro are extremely useful currencies to give values in because firstly they are highly stable and secondly most people in countries with local currencies will have a good understanding of the current value of one or the other relative to their own currency
