Alex Manninger joined Liverpool on a free transfer in July 2016 after nearly four years with Augsburg.
The 39-year-old goalkeeper is best known in England for his time with Arsenal, who he joined in 1997 from AK Grazer in his native Austria.
Manninger spent five years at Highbury, playing a key role in the Gunners’ successful 1997-98 Premier League title run-in when regular No.1 David Seaman was out injured.
After being loaned to Fiorentina for the 2001-02 season, Manninger left Arsenal for Espanyol.
Spells with Torino, Bologna, Red Bull Salzburg, Siena and Udinese followed, before the former Austria international signed for Juventus as Gianluigi Buffon’s deputy in 2008.
Manninger - who won 34 international caps between 1999 and 2009 - left Juve in the summer of 2012 and subsequently joined Augsburg.
He was an unused substitute when Liverpool beat the German club 1-0 in the second leg of their Europa League last-32 tie at Anfield in February this year.
