Mark Gonzalez says he has completed his Liverpool medical and will begin training with the club next month.
Liverpool have agreed to sign the 21-year-old Chilean from Spanish side Albacete on a four-year deal.
“I am delighted a deal has been agreed – I only have to wait for the papers,” Gonzalez told Spanish news agency Efe.
Although he will be unable to play for Liverpool until next season at the earliest because he has yet to be granted a work permit, Gonzales will remain on Merseyside.
Gonzalez is currently in Chile, recovering from a knee injury.
He said he was surprised by Liverpool’s patience “because not all teams would wait for a player as they did”.
He added: “Only the biggest teams do that. Now, I have to respond to their confidence with football.
“I’m aware he has shown he has the confidence to sign me while I’m injured.
“This is an extra motivation to prove to everybody that they haven’t made a mistake.”
Next summer Gonzalez will be eligible for a Spanish passport on the grounds of residency.
Liverpool chief executive Rick Parry said: “there is no chance of us being able to apply again in the January transfer window.”
