Three-time champions Spain comfortably beat Croatia 3-0 in the German capital, Berlin.Croatia had just found their way into the Group B game when the Spanish side quickly built a 2-0 lead thanks to Alvaro Morata in the 29th minute and Fabian Ruiz three minutes later. Dani Carvajal added a third shortly before the break.Croatia thought they pulled one back in the 80th minute after Bruno Petkovic had a penalty saved by Unai Simon but got the ball back to score, but it was disallowed as Ivan Perisic had encroached into the box before the penalty was taken.Spain’s Lamine Yamal became the youngest player to appear in a European Championship at the age of 16 years, 338 days, and the Barcelona winger set up Carvajal’s third goal.Defending champions Italy play Albania in the other Group B game later on Saturday, kickoff is at 9pm local time (19:00 GMT).
