The Stamford Bridge starlet was part of a victorious Spanish side last year, as Spain beat Switzerland 2-0 in the final.
And Romeu is hopeful his country can repeat the feat next summer in Israel after completing an 8-1 aggregate play-off triumph over Denmark this week.
"Everybody wants to play at a tournament likes the U21 finals," said Romeu. "We want to win it, obviously, but it's not going to be easy.
"A lot of teams will try to get the title but we will do our best."
The Spaniard joined Chelsea from Barcelona in 2011, but has only made a handful of appearances for the Blues since his arrival.
Purchased to provide competition for John Obi Mikel in Chelsea's defensive midfield role, Romeu has yet to fully find his feet at Stamford Bridge.
But the 21-year-old is a key part of the Spain youth set-up, having featured in every age category from under-17 through to under-23.
Romeu played a part in Spain's disappointing Olympic bid in London this summer, as the reigning European and World Champions crashed out in the group stages.
Spain enjoyed more success in the under-21 tournament the year before, something Romeu is keen to repeat. The Chelsea midfielder was one of the elder statesman on that talented team as the Iberians confidently brushed aside the competition, conceding only two goals across the whole tournament.
Last year only England managed to get a result against the Spain under-21 team - Stuart Pearce's side drew 1-1 in the group stage. And England will once again provide competition for Romeu and Spain, as Pearce's team qualifed for the tournament in Israel with a 2-0 aggregate victory over Serbia.
