You can't think of the word 'shrewd' in a footballing context without thinking about Tottenham Hotspur chairman Daniel Levy.

The Spurs supremo has developed a reputation for being a ferocious figure in regards to negotiations, to the point where an unnamed owner of a Premier League club told The Daily Mail in February 2015, after a deadline day: "Daniel likes to squeeze your balls until your eyes start to water."

And it looks like the president of Fenerbahce, Ali Yıldırım Koc, can relate to that analogy.

The Turkish businessman revealed to Futbol Arena this week that Fenerbahce paid £4.4 million to sign Tottenham striker Vincent Janssen last summer which, given how it was a loan, is quite a substantial figure, and the latest example of how Levy has the capacity to squeeze every penny from what he feels a player is worth.

Twelve months earlier, Levy paid £18.5 million [Daily Mail] to sign the Dutchman, who had a horrendous first season in North London and only scored once from open play, in 38 games across all competitions.

But he has already made a quarter of that back on a player who has only managed three goals in 14 league games for the Turkish outfit this season - a perfect example of Levy's modus operandi.

Janssen probably won't ever repay his transfer fee, not in terms of on-the-pitch contributions, but the Spurs chief only needs to make around £14 million from him on a permanent sale before breaking even, and few would be surprised if Levy - who sold Kevin Wimmer to now-relegated Stoke City for a club-record £18 million last summer - actually made a profit on the misfiring Dutchman, as he did so handsomely with Wimmer.

Levy might be asked about far bigger Tottenham players this summer and although fans of the North Londoners would hate to lose Harry Kane, Dele Alli or Christian Eriksen, they can rest easy in the knowledge that delegates from, say, Real Madrid would leave the negotiating table with watering eyes.
