Tottenham held off a late attempt from Chelsea to sign Everton forward Richarlison.
Everton had rejected an initial £40m from Spurs at 4pm on Wednesday but they came back with a revised offer of £50m plus add-ons which Chelsea opted not to match.
Richarlison underwent his medical in Brazil on Thursday with Tottenham staff present and is due back in the UK next week. Watford will receive around £2m from the deal.
Tottenham are also in advanced in talks over a £15m deal for Middlesbrough right-back Djed Spence, have a loan in place for Barcelona defender Clement Lenglet and are monitoring developments with Leicester City midfielder Youri Tielemans.
