Tottenham are confirmed to be one of the clubs chasing Dinamo Zagreb teenagers Alen Halilovic and Tin Jedvaj, according to the Croatian club.
Zagreb president Mirko Barisic had previously announced that the club had agreed terms with an unmanned club for the two starlets, believed to be in the region of around £17m.
Now executive director Zdravko Mamic has confirmed Spurs are one of the clubs interested in signing the pair, but insists a deal is far from being struck.
Mamic told a press conference: "Discussions and negotiations with Tottenham are still ongoing, but this job is absolutely not done.
"And Tottenham is not the only one interested, but we hope that transfer will be realised and that Tin and Alen will go to Tottenham, but no-one can guarantee that.
"If the business was done, we would say so and if the transfer is completed, they will both stay at Dinamo.
"I can also reveal that there are many clubs after both of them, there is not a club from the top 20 in Europe that didn't ask us about them."
Manchester City and AC Milan were also thought to be interested in attacking midfielder Halilovic who, last September, became the youngest debutant in Zagreb's history at the age of 16 years and 101 days when he came on as a substitute against Hajduk Split.
He became their youngest ever goal scorer 10 days later after hitting the net against Slaven Belupo.
In June, he got his first senior cap for Croatia after making an appearance against Portugal.
Roma and Arsenal have also expressed an interest in 17-year-old Jedvaj, who made 13 appearances in his debut season at Zagreb.
Elsewhere, it is reported Spurs manager Andre Villas Boas will look to make five major summer signings as they push for a top-four finish this season.
Brazilian Paulinho and Barcelon's David Villa are reported to be two of the starts set to make their way to White Hart Lane, with Jermain Defoe and Emmanuel Adebayor two of the current crop of players who could be sold to make way.
