The former Chelsea coach has expressed his admiration for the Brazil international, but denied trying to lure the 25-year-old attacker to White Hart Lane
The Portuguese coach paid his former charge a visit at Brazil's Olympic Games base in St Albans ahead of their friendly with Team GB, immediately sparking speculation that he was sounding out the 25-year-old attacker about a move to White Hart Lane.
Villas-Boas insists that he was doing nothing of the sort, but he did express his admiration for the Selecao star.
"Hulk is a very special player for me," the former Chelsea coach told Terra. "We had a very good year together in Porto and we have a good relationship - that I do not deny.
"But we have just been talking, nothing more."
Villas-Boas, who replaced Harry Redknapp as Spurs boss earlier in the summer, led Porto to a treble during his one season at the Dragao, in 2010-11.
