Spain coach Gustavo Aranzana has named a 14-strong preliminary squad for the U20 European Championship in Latvia.

Power forward/center Victor Claver of Pamesa Valencia and shooting guard Marc Rubio of DKV Joventut are in the group that will gather for the first time on Monday in Valdemoro.

Nick Calathes is relishing the opportunity to try out for the Greece Under-20 team.

A college basketball star in America with the Florida Gators, the 6ft 6in Calathes is a third-generation Greek who was the co-SEC Freshman of the Year and the SEC's Newcomer of the Year this past season after averaging 15.3 points per game while setting a school record with 221 assists.

Georgios Sigalas made his mark as a player with Greece's national team.

Now he has a chance to do the same as a coach.

Slovenia coach Miro Alilovic has picked a 17-strong preliminary squad for this summer's U20 European Championship in Riga and there are a couple of familiar names  in it.

Klemen Lorbek, the younger brother of Slovenia internationals Erazem and Domen, has been included. Also named is Zoran Dragic, whose brother Goran last summer helped fire Slovenia into July's FIBA Olympic Qualifying Tournament in Greece.

Serbia captured gold as hosts of last year's FIBA U19 World Championship in Novi Sad under coach Miroslav Nikolic and now, most of the same players will try to duplicate the success in Europe.

This time, though, the players will be led by Slobodan Klipa, a man who has thrived as boss of FMP Belgrade.

There's a new attitude in Ukraine, where the country is hoping to become a major player on the European hoops scene again.

Following Valentyn Melnychuk's successful run to the EuroBasket 2007 quarter-final qualifying round with Portugal, the Ukrainian federation lured him home to coach their senior team.
