Tottenham Hotspur are reportedly weighing up a £30m deal to sign Brazilian forward Hulk from Zenit St Petersburg.
Andre Villas Boas worked with the 27-year-old during his time at Porto and is keen to reunite with the forward, who earned his nickname due to his muscular physique.
However, with Zenit demanding a fee closer to £40m, The Telegraph reports that any deal is still far from being completed.
Tottenham Hotspur have been active during the summer transfer window, with Roberto Soldado arriving for £26m, Paulinho joining from Corinthians and Nacer Chadli making the move across the channel from Dutch side FC Twente.
Gareth Bale is set to complete a move to Real Madrid in the coming days, which could eclipse the £80m record transfer fee paid for Cristiano Ronaldo in 2009.
