Spain midfielder David Silva has admitted that winning the European Championships for a third time in a row will be a "complicated challenge".
La Roja were victorious in Austria and Switzerland at Euro 2008 and they retained the trophy four years later in Poland and Ukraine.
Silva was part of both Spain squads in those tournaments, and also helped them win the World Cup in 2010.
Vicente del Bosque's side are in the running for European glory again this summer, but Silva, who plays his club football for Manchester City, does not expect an easy ride.
"Winning this championship three times in a row is a complicated challenge, but we will try," The Mirror quotes Silva as saying.
"I feel much better and I am very eager to play with Spain and to play great matches. It will be a very competitive and great tournament.
"It will not be easy to repeat the past successes, because there are very strong teams at the European Championships."
Spain's opening group game will be against Czech Republic on June 13.
