Tottenham don't like doing business with Manchester United, and their resolve is going to be put to the test this summer.
Ever since being coerced into a deal to sell them Dimitar Berbatov on deadline day in 2008, the two clubs have not conducted a single transfer - despite The Telegraph reporting in 2013 that the Red Devils made a bid of £100 million for Gareth Bale.
United are said to be back in the hunt for Tottenham's latest sensation, striker Harry Kane, who netted more than 30 goals in all competitions last season.
The Manchester Evening News reported 24 hours ago that United chief executive Ed Woodward is planning to negotiate with Spurs chairman Daniel Levy to sign Kane.
Kane is a product of Tottenham's academy, and recently signed a contract committing his long-term future for the club. He is thought to have no desire to move on, just as the club have little incentive to sell to a rival.
Given the way they blew the money received for Gareth Bale, United's millions on offer look a lot less tempting than they once might have, especially considering that in Kane, Spurs have a striker they can build around for the next decade.
So why could United's interest in Kane be a positive for Tottenham fans?
Well it relates to the other player in the Spurs team who Manchester United have been heavily linked with. French international goalkeeper Hugo Lloris has repeatedly been touted as a replacement for David de Gea, who is wanted by Real Madrid.
That was reported by the Guardian earlier this transfer window, with the newspaper claiming Lloris wanted to leave Spurs to play in the Champions League.
United might have stood a chance of signing Lloris had they submitted an offer above his market value, with The Mail reporting Spurs would consider offers upwards of £35 million.
A bid, or even an approach for Harry Kane is only going to antagonise Tottenham, and make them less receptive to even listening to United's advances for Lloris.
It is for this reason the latest developments regarding United's destined-for-failure move for Kane, that Spurs fans should feel positive, for the knock-on effect could be that Lloris has an increased chance of staying put.
