The Tottenham Hotspur supremo certainly knows how to make a profit in the transfer market.
Tottenham Hotspur chairman Daniel Levy generates money like few others in the transfer market, regularly making sizable profits on players often bought for relative pennies, and he has done it again following Kevin Wimmer's move to Stoke City.
As confirmed by the Potters' official website, Wimmer has move to the Britannia Stadium in an £18million deal, and that is in stark contrast to the fee Tottenham paid Cologne for the Austrian international just two years earlier.
Back in 2015 the Telegraph claimed Spurs signed Wimmer for just £4.3million, meaning Tottenham have made a £13.7million profit on a player who only ever turned out 31 times for them.
That is a brilliant piece of business, with Wimmer only showing sporadic glimpses of his talent during his time in North London, and while many Tottenham fans expect him to prove his worth at Stoke, it is still another savvy piece of business from Levy.
This is not the first time Tottenham have made a big profit on a player and it will not be the last. Kyle Walker and Gareth Bale are two notable examples while Eric Dier could one day join that list.
The problem for Spurs fans is that while their club regularly rakes in impressive transfer fees for fringe players, the money is not always sufficiently spent on upgrades.
With time running out, this summer could follow a familiar pattern, although three days remain to make something happen.
