Reports have emerged that the 25-year-old Brazilian has agreed a 5-year-deal with the north London club according to Sky sources. Sky Sports News also claim that Willian has passed his medical.
All of this is reported to be for a club record £30million fee, which is very unlike Spurs and chairman Daniel Levy in particular, who are notoriously tough to deal with in the transfer market as Levy looks to save every penny.
Anzhi Makhachkala bought Willian for £30million in January, and with Anzhi having slashed their budget and transfer listed all of their players, Willian could've arguably been sold for less.
It's not as if Spurs are in desperate need of an attacking midfielder/winger having already spent £58.8million this summer.
They are also heavily in the hunt for Roma forward Erik Lamela for another £30million with the Daily Telegraph claiming that Spurs have agreed a 6-year-deal in principle with Lamela.
This extra spending spree of up to £60million might have been triggered by a possible formal offer from Real Madrid for Gareth Bale, which Spurs are looking to accept to fund the new signings.
These two potential signings will take Tottenham's total spend for the summer close to an eye watering £120million, making them the biggest spenders in the Premier League.
