Osasuna have used four goalkeepers in 18 matches Osasuna Alvarez debuted on Thursday

Osasuna used their fourth goalkeeper of the season against Lorca Deportiva in the Copa del Rey on Thursday evening.

Youngster Inaki Alvarez kept a clean sheet in the 3-0 victory for Jagoba Arrasate's side as they progressed to the second round.

Ruben Martinez has made 13 appearances in LaLiga Santander this season and had been Osasuna's starting goalkeeper for the last year and a half.

However, he was forced off with injury against Getafe on November 10 and was replaced by Sergio Herrera.

Herrera, who was returning from a serious knee injury himself, continued in goal for the next game against Athletic Club, but was injured again afterwards.

That meant that third-choice goalkeeper Juan Perez was drafted in for matches against Espanyol and Sevilla, before Herrera was fit to return against Atletico Madrid last weekend.

After being rested in midweek, allowing Alvarez to play, Herrera is expected to start against Real Sociedad on Sunday.
