Awesome,
Somewhat expected, except it would be nice to see the disclosure transfer fees. I believe Barca would move above Juve. and also Bayern (I forgot where I saw it that they have quite a few hidden, exchanges - but dont take all the word from that).
Just looking at total expenditure, not net expenditure (i.e. left out money made from transfers, just looking at money spent).
Additionally, these are only transfer fees that have been disclosed to the public. No undisclosed transfer fees (e.g. Neymar) have been included because the sources are too unreliable. All transfer fees were added up from transfermarkt.com just for consistency's sake.
