Tottenham reached an agreement to sign Russia striker Roman Pavlyuchenko from Spartak Moscow.
Pavlyuchenko arrived in England on Friday for a medical and negotiations over personal terms and the deal was sealed on Saturday.
“We are delighted to announce that we have reached agreement with Spartak Moscow for the transfer of Roman Pavlyuchenko to the Club,” a statement on Tottenham's website confirmed.
The fee paid by Tottenham has not been disclosed but it is understood to be around 14 million pounds (17 million euros) and the move could pave the way for Dimitar Berbatov to leave Spurs for Manchester United.
Pavlyuchenko will not feature when Spurs take on Chelsea on Sunday.
Meanwhile, Real Zaragoza president Agapito Iglesias is reported to be in London to discuss the possible transfer of Diego Milito and Sergio Garcia from the Spanish club to Spurs.
