Spain remain on course to become the first country to win three European under-19 championships in a row, after qualifying for this year's finals in July.
After two successive wins, they needed to avoid defeat against a Croatia side in their final game who were two points behind them, with only one side from their qualifying group going through.
They suffered an early blow as right-back Hector Bellerin, of Arsenal, was injured early on and had to be substituted off in the 22nd minute.
Croatia then took a second half lead through Petar Brlek before Spain equalised through Moises Bardonado in the 77th minute.
The game finished at 1-1, and it was enough to see Spain qualify for the finals in Lithuania.
The extent of Bellerin's injury is not known, but it appears not to be serious enough to keep him out of the finals next month judging by the positive mood of his tweet after the game.
The tournament will take place in Lithuania between July 20 and August 1, meaning Bellerin stands to miss the majority of Arsenal's pre-season.
With the future of Bacary Sagna uncertain, many had mentioned the Spaniard as a possible alternative in case the Frenchman moves on, in support of Carl Jenkinson.
A few pre-season outings for the Gunners could have helped his case, but the chance to make history with Spain's under-19 side is not one he can turn down.
He will miss the tour overseas, but when Arsenal host the Emirates Cup on the 3rd and 4th of August and there is an outside chance he could still get a game there, dependent on Spain's progression, while a fixture in Helsinki against Manchester City on August 10th could just be when he gets a chance.
Will he miss out by not being on Arsenal's pre-season tour?
