Another starlet Spurs could sign this summer is Dinamo Zagreb's Alen Halilovic. The 17-year-old is considered one of the greatest young talents in European football and has already broken into Croatia's senior side. Tottenham are believed to have started negotiations with Zagreb over a deal for Halilovic, and have maintained a positive relationship with the Croatian outfit since doing business for Luka Modric in 2008. The prodigious attacking midfielder has attracted interest from a number of top clubs and made history last month when he became the youngest ever player to represent Croatia's national team, making his debut in a friendly against Portugal. With starlets like Christian Eriksen, Erik Lamela and Aaron Lennon already budding at White Hart Lane, the arrival of Halilovic would provide Villas-Boas with a platform of which to build on over the next few years.
