Tottenham Hotspurs have confirmed the signing of left-back Sergio Reguilon from Real Madrid on a five-year deal.

Reguilon, who will wear the number three shirt, travelled to London on a private jet owned by Tottenham chairman Daniel Levy on Friday morning, alongside Gareth Bale who has also rejoined the club on a one-year loan deal. He will wear the number 9 shirt.

Reguilon, 23, was named the best left-back in La Liga for his performances last season while on loan at Sevilla.

The signings of Gareth Bale and Sergio Reguilon could see Tottenham’s formation change as Jose Mourinho completes one of the biggest tactical shifts of his long and illustrious managerial career.

Bale’s return is a major coup for Spurs and reignite enthusiasm from supporters but the onus would be on Mourinho to make best use of his undoubted ability. The acquisition of Bale’s young Real Madrid team-mate could prove to be a key factor in achieving that.

It will surely bring a change of formation, one hinted at since Mourinho arrived.
