Football and finance may clash for Tottenham Hotspur.
For any Tottenham fan, keeping Harry Kane is a no-brainer in footballing terms.
But the world of the businessman is a little different from the world of the football fan. Mike Ashley has proven that at Newcastle United, while chairman Daniel Levy has often done the same at White Hart Lane.
And it is Levy that could provide another case in point this summer, with regards to a certain Kane.
The Tottenham striker has been linked with a big-money move to Manchester United this summer by Sky Sports among others but the recent noise has cooled in that regard. Were anything to develop before next season, however, Levy's head might just be turned.
The reason, as ever, is purely financial. Once again, in footballing terms, Spurs need Kane. Their top scorer last season, the 21-year-old is - famously - one of the north London side's own. For the team and even for simple marketing purposes, he's the man: the face behind the side.
But, from a business perspective, would it not be feasible to suggest this summer is the best time possible to sell the young forward?
In a strange way, Kane's value may never be greater. If the Tottenham striker can't reproduce his 20-goal season next time around, any potential future sale will likely take a huge hit in terms of figures. And to keep the England man at White Hart Lane with a view to him improving even further - from a business sense - would be a gamble. Who could, without any doubt at all, guarantee he will continue in the same fashion from this point onwards?
That's not to say Kane is going anywhere or will do this summer. But it's certainly how a shrewd negotiator like Levy might view the situation.
