Germany coach Joachim Loew has named four talented youngsters, including three uncapped players, in his preliminary 27-man squad for Euro 2016. Versatile midfielder Joshua Kimmich, striker Leroy Sane, Julian Weigl - another midfielder - and wide man Julian Brandt were all included when Loew announced his provisional squad Tuesday. Sane, 20, is the only one of the quartet to have earned a senior cap, making his national debut as a substitute against France in November 2015. He scored eight times this season and his explosive speed and skills were rare bright spots in Schalke's otherwise disappointing season. Twenty-one-year-old Kimmich, who played at both center back and as a holding midfielder for champion Bayern Munich, earned repeated praise from his coach, Pep Guardiola, during his first season at the club. Borussia Dortmund's Julian Weigl enjoyed a superb Bundesliga debut season as his club finished second, while fellow 20-year-old Julian Brandt's nine goals earned Bayer Leverkusen third spot. Injured captain Bastian Schweinsteiger, who is racing to be fit for the tournament in France, was also included in Loew's provisional list. The final squad will be announced later this month. Germany faces Ukraine, Poland and Northern Ireland in Group C of the competition, starting on June 10. Spain omits Costa, Torres Chelsea striker Diego Costa was left out of Spain coach Vicente del Bosque's provisional 25-man squad for Euro 2016 Tuesday. The naturalized Brazilian missed Chelsea's last two games of the season due to a persistent hamstring injury and has struggled at international level with just one goal in 10 games since declaring to play for Spain in 2013. "We didn't want to bring too many players with a certain doubt over their physical condition," Del Bosque said of Costa's omission from the two-time defending champion's squad. Del Bosque will have to cut his final squad to 23 players on May 31. World Cup winners Fernando Torres, Juan Mata and Javi Martinez were also high-profile names left out by Del Bosque. The absence of Costa and the in-form Torres means Del Bosque has only two central strikers to choose from in 35-year-old Aritz Aduriz and Juventus' Alvaro Morata. Arsenal's Santi Cazorla was also excluded having just returned from a long-term knee injury. The uncapped Saul Niguez and Lucas Vazquez of Atletico Madrid and Real Madrid did make the 25, whilst Villarreal captain Bruno Soriano was surprisingly included amongst 10 midfielders. Del Bosque also named 11 uncapped promising younger players to bulk up his squad for the friendlies against Bosnia and Hercegovina and South Korea on May 29 and June 1 respectively with Real and Atletico players set to take part in the Champions League final on May 28. Spain begins its campaign against the Czech Republic on June 13 before also facing Turkey and Croatia in Group D.
