Lionel Messi believes Barcelona showed their appetite for the Copa del Rey by blowing away Sevilla 6-1 on Wednesday to pull off a brilliant comeback and book their place in the semi-finals.

Sevilla had won the first leg 2-0 but their lead was wiped out within 31 minutes at the Camp Nou, after Philippe Coutinho scored a penalty, before Ivan Rakitic poked in a second. Coutinho headed in his second and Sergi Roberto added a fourth, only for Guilherme Arana to give Sevilla brief hope. Luis Suarez and Messi wrapped up the win.
