Spurs have been dealt a few blows in recent days.
Although they beat West Ham 2-0, in terms of the transfer market, nothing is going too swimmingly.
The north Londoners have missed out on Thomas Meunier while Chelsea have opened contract talks with Willian to keep him away from Tottenham.
Sitting seventh in the Premier League, Jose Mourinho clearly needs to strengthen, but that looks like a tough ordeal at the moment.
Not only are players not signing, but the very presence of Covid-19 means that money presumably won't be thrown around as regularly as it would.
Therefore, the idea of luring someone to England for a potential fee of £65m this summer feels slightly out of touch with where the market is.
Though, it would have to be applauded if Spurs were able to achieve that.
According to a report from The Telegraph, Spurs are interested in signing Sevilla centre-half Diego Carlos.
The Spaniard is admired by Mourinho but his release clause currently sits around the £65m mark.
Sevilla are expecting a fee of more than £35m and rightfully so given his clause, but with cheaper alternatives in the form of Robin Koch and Kim Min-Jae, they could look elsewhere.
Aged 27, Carlos is currently in the prime of his career and could represent a solid replacement for the likes of Jan Vertonghen and Juan Foyth.
GIVEMESPORT'S Matt Dawson says...
Spurs have struggled for clean sheets and have lacked defensive discipline under Mourinho, particularly this calendar year.
Tottenham have conceded 42 goals in the 28 matches the Portuguese has taken charge of Spurs so it's clear they need new recruits.
Add the fact that Vergonthen and Foyth could leave and there is a real void in the backline.
The Brazilian would certainly add some steel to the defence in north London, reigning supreme in the air with 2.6 aerial duels won per game in La Liga. That statistic, coincidentally, puts him on par with Tottenham's departing centre-back.
Their pass success rate is also incredibly similar with Carlos registering an accuracy of 83% compared to Vertongthen's 82.7%.
Sevilla's centre-back looks more robust when it comes to bodily build, but he doesn't differ too much in style to what Spurs already have.
Given that fact, he shouldn't have too many difficulties fitting into their style of play.
