Susaeta made over 500 appearances for La Liga side Athletic Bilbao, scoring 56 goals and making 87 assists across a 12-year stint from 2007-2019
In 2019, he left Bilbao after his contract ended and joined Japanese side Gamba Osaka in September where he made seven appearances.
His best season came in 2011-12, where under coach Marcelo Bielsa he scored 13 goals in a marathon 63 game season, which also included appearances in the Europa League final and Copa del Rey final.
The 32-year-old has a relatively good injury record, having only missed three matches through injury since 2012.
Melbourne City FC Director of Football Michael Petrillo said Susaeta’s experience will be an invaluable asset to the side for the rest of the season.
“We’re incredibly pleased to have a player like Markel at Melbourne City,” Petrillo said.
“Markel is a player that is well suited to the style of game we have implemented under Erick and a player who will add flair, potency and experience to our front third.
“We have been tracking Markel for quite some time now so to be able to get him into the squad is testament to the Club and its ability to attract a player of Markel’s pedigree.”
“His outstanding record at Athletic Bilbao speaks for itself and his experience in La Liga and Europe will lift the whole squad as we look to continue our push towards the latter stages of the season.”
Susaeta will be available for selection ahead of Saturday's clash with Newcastle pending visa approval.
