The 23-year-old, who impressed on loan at Sevilla last season, is in talks with Spurs, having previously been linked with Manchester United, Chelsea and Everton.

According to reports, Manchester United were keen on Reguilon, but were unwilling to agree on three key aspects of the deal – a Real Madrid buy-back clause of around 40m euros, a preemption clause which would prompt United to contact Real if anyone made a future bid for the player, and the fee of 30m euros.

Tottenham are seemingly happy with the clauses, and therefore Reguilon looks to be on his way to north London. Real Madrid have three full-backs on their books and need to sell, but with a view to re-signing him in the future, this deal makes sense for all concerned.

As reported on Sky Sports in early August, Chelsea were in the race for Reguilon before they signed Ben Chilwell from Leicester, while Everton also bid £18m for the Real academy product.

But his performances in 2018/19 weren’t enough to get a starting spot under Zidane, who brought in Ferland Mendy to compete with Marcelo, meaning Reguilon moved to Sevilla on loan for the 2019/20 season.

It turned out to be a sound move for the defender, playing 38 times in all competitions under former Real boss Lopetegui as they won the Europa League again and qualified for this season’s Champions League.

Style of play: Energetic, attack-minded, if slightly chaotic

Take a look at Reguilon’s 19/20 season stats during his loan spell at Sevilla
Though the focus on modern-day full-backs may sway towards attack over defence, Reguilon may be required to perform both tasks in equal measure under Jose Mourinho.

But there is little doubt Reguilon impressed most in the opposition’s half last season. An energetic, almost frantic full-back, Reguilon’s trademark is to gallop into the area from deep, rather than cross early.

He is not afraid to take on defenders, and registered 1.6 successful dribbles per game last season, the fourth-highest of all La Liga defender playing over 10 games.

Reguilon also registered 1.3 key passes per game, the fifth-highest of all La Liga defenders, and had five assists in all competitions, plus an assist on his Spain debut against Ukraine this month.

But his fearlessness in an attacking sense brings its concerns – only four defenders in La Liga lost possession more often than Reguilon – but with under 50 top-flight games under his belt, there is coaching potential.

The end of Spurs’ lop-sided defence?
Could Reguilon’s arrival mean a change in style for Jose Mourinho’s Spurs?

The arrival of Reugilon – whose strength lies in attack before defence – may spell an end to Mourinho’s lop-sided defence, which had up to now focused on loading the wide right area.

Matt Doherty’s debut on the right of Spurs’ four-man defence on Super Sunday against Everton showed promise in an attacking sense, but the former Wolves man left gaps behind him for Toby Alderweireld to cover.

If Reguilon joins, Spurs could attack with symmetry in the full-backs, or could move to a five-man defence to cover the attacking wide men.

A five-man defence is something Mourinho has employed on just seven occasions for Spurs, winning once, drawing three times and losing three times. Those defeats came against RB Leipzig away, Chelsea away and Wolves at home last season.

What they’ve said
“Reguilon has grown at a barbaric rate. He’s a much more complete player than when he first joined. Hopefully he can continue with us.” – Julen Lopetegui, Sevilla manager, August 2020
