On-loan Napoli goalkeeper Pepe Reina feels that Jose Callejon would be a "useful" addition to Spain's World Cup squad next summer.
Reina, who is on a season-long deal from Liverpool, believes that his teammate's form could see him selected for next summer's tournament in Brazil.
"Callejon is performing great with Napoli," Reina told Sky Sport Italia.
"For this reason, and because of where he plays on the pitch, I won't exclude the fact that he could become useful to the national team again ahead of the World Cup."
Vicente del Bosque's side were beaten 1-0 by South Africa on Tuesday evening.
