7. Kevin De Bruyne (Manchester City) - 86
Kevin De Bruyne's transfer came with one of the most outrageous transfer fees in football history;
£58 million, the sixth highest of all-time. He cost £12 million MORE than Zinedine Zidane at his peak. Who do Manchester City think they've bought? The Belgian midfielder sparkled for Wolfsburg with an immense goals and assists tally, but this transfer has came just one year after Chelsea deemed him not good enough for their side and shipped him out for £18 million. No player should see their value skyrocket that highly, particularly if they're returning to a league they failed to impress in. De Bruyne has received a 3+ boost for his big move. That's incredibly high.
