Tottenham completed the signing of Richarlison from Everton on a five-year deal for a fee that could reportedly rise to £60 million ($73 million) on Friday.
The Brazilian international will add greater depth to the Spurs forward line, although he has a tough task ahead to dislodge either Harry Kane or Son Heung-min from his two favoured positions up front and on the left of the attack.
Tottenham will pay an initial £50 million fee with a further £10 million in performance-related bonuses.
Richarlison becomes Spurs' fourth signing of the transfer window after Croatian winger Ivan Perisic, midfielder Yves Bissouma and goalkeeper Fraser Forster.
The London club have heavily backed manager Antonio Conte after the Italian secured Champions League football next season.
"We are delighted to announce the signing of Richarlison from Everton, subject to a work permit," Tottenham confirmed in a statement.
"The Brazil international has signed a contract with us until 2027."
