Spain boss Vicente del Bosque has revealed that Atletico Madrid forward Diego Costa has settled into the La Roja squad "without any problems".
The 25-year-old received his first call-up by Del Bosque last week and is expected to make his international bow against Italy on Wednesday evening.
"He's settled in with the national side easily and without any problems," he told reporters.
Del Bosque has also claimed that he expects to face a more "powerful" Italy side from that one that Spain beat 4-0 in the final of Euro 2012.
