Vukovic spent five years at Central Coast Mariners prior to Arnold's arrival at the A-League club in 2010. While their paths never crossed in Australia, The World Game understands Arnold tried to sign the Glory goalkeeper during the latest off-season.
Prior to Arnold’s arrival in Japan this year, Sendai sold its first choice goalkeeper, Takuto Hayashi, to the club's fierce rival Sanfrecce Hiroshima, leaving the side with no recognised first-choice keeper.
Vegalta lost its opening match of the new season 2-1 to Albirex Niigata on Saturday and it’s understood that the club has been looking at bringing in a more experienced 'keeper for some time.
Vukovic will become the second player with Australian connections to join the club since Arnold took the reins - while strength and conditioning coach Andrew Clark followed the coach from Central Coast Mariners.
The loan deal includes an option for Sendai to buy Vukovic at the conclusion of the five-month term and should provide it some immediate cover ahead of the trip to powerhouse Kashima Antlers this weekend.
