Liverpool have officially announced the signing of veteran goalkeeper Alex Manninger on a one-year contract as third-choice back-up.

The 39-year-old will come in, subject to international clearance, to act as deputy to both Simon Mignolet and Loris Karius having trained with the club over the last few weeks.

After being released by his previous club, FC Augsburg, at the end of last season - Manninger has worked under Jürgen Klopp at Melwood, impressing enough to earn a short-term deal.

The Austrian shotstopper has travelled with the rest of the Reds' first-team for their pre-season tour of North America and could make his maiden appearance in one of their friendlies against Chelsea, AC Milan or AS Roma.

Manninger has previously played for Fiorentina, Udinese, Juventus and even Arsenal. In the 1997-98 season, Manninger kept six consecutive clean sheets as stand-in for David Seaman, a then joint club record.

He was named Premier League Player of the Month for his displays and despite making just seven appearances by the end of the campaign when the minimum to receive a winners' medal was 10, he was given special dispensation to receive one because of his contributions.

Manninger even had a trial with Everton in 2012 before joining Augsburg, where he spent the last four years, making 34 appearances.

Manninger insists he will try to make an impact even when he's not on the pitch

He follows £4.2 million summer signing Ragnar Klavan in swapping the Bundesliga outfit for Liverpool, after the experienced Estonian centre-back signed for the Reds earlier this week.

With goalkeepers Danny Ward, Ryan Fulton and Adam Bogdan all going out on loan already this summer, Klopp was keen to recruit an experienced fall-back option and he has identified Manninger as just that.

He signed his contract with the club over in the United States, where he has continued training with the squad ahead of their 10-day tour, and admitted that "it was a surprise" to be asked to join the club.

Manninger declared that it was "a great pleasure" for him to be asked to sign for Liverpool, explaining that it gives him what he was "looking for" from a next club.

"This is the moment I was waiting for until the end," he hailed, insisting that he's "still got something left" but that it's "probably not the time" for him to "push for the next three or four years to get a place in the goal."

The former Austria international said that it's "not possible" for him "to play 50 games a year" but declared that if he's "called up" then he will "definitely be there."

"I'll definitely be in the changing room every game, giving my input," insisted Manninger - who has taken the No.13 shirt on Merseyside - hoping that "even if it's only a couple of per cent" it will "do the rest" and help his teammates.

Liverpool will soon make their seventh signing of the summer, with £25 million attacking midfielder Georginio Wijnaldum set to undergo a medical back on Merseyside ahead of his switch from Newcastle United.

A deal could be confirmed later on Friday, with the Dutchman then set to fly across the Atlantic to join his new teammates in California.
