Spain coach Vicente del Bosque is not pleased by the actions of some national team players during an ill-tempered Copa del Rey semifinal between Real Madrid and Atletico Madrid.

Madrid beat Atletico 3-0 in the first-leg semifinal on Wednesday when Madrid players Alvaro Arbeloa and Sergio Ramos were among those to clash with Atletico striker Diego Costa, a Brazilian-born, naturalized Spaniard who is expected to be at the World Cup for Spain.

Del Bosque says ''there are episodes I did not like seeing (...) everyone has to defend their team but there were clashes and personal conduct that were not adequate.''

Spain's squad has previously had to make peace between club players from Madrid and Barcelona following nasty episodes in clasicos.
