Kilkenny is the second signing in a week for the A-League outfit as the club attempts to bolster its flagging season.

The 32-year-old will be in selection contention for Sunday's home clash against Western Sydney Wanderers and has set a target of finals football.

On the outer at City, Kilkenny was keen for a move after making just three appearances for a total of 70 minutes this season.

He flew into Perth on Wednesday evening and said he was eager to to get back into action and help the strugglers, currently lagging in ninth spot on the ladder.

"I'm excited to have joined the club and am really keen to make the most of this opportunity," Kilkenny said.

"We have a strong squad here and I'm looking forward to doing my bit to help drive us into the finals.That's the aim and I'm confident that we can achieve it."

Glory's Head of Football, Jacob Burns, believes Kilkenny will prove an excellent addition to the squad.

"Neil has a wealth of experience and a winning mentality which will prove hugely beneficial for the whole playing group," Burns said.

"He will have a vital role to play in the midfield engine-room and can also slot in at centre-back if required which is another major plus.

"A number of other clubs both in Australia and overseas were keen to sign him, so we're delighted that we managed to beat off the competition and get him on board."

Kilkenny's signing follows hot on the heels of a deal with defender Dino Djulbic who is returning to WA for his third stint with Glory.

Described by Glory as "versatile, industrious and uncompromising," Kilkenny has spent most of his career in England where, after coming through the youth ranks at Arsenal, he played for Oldham Athletic (loan), Birmingham City, Leeds United, Bristol City and Preston North End.

The 14 capped Socceroo made nearly 350 first-team appearances in British football before joining Melbourne City in 2016 and claiming their Player of the Year and Fans' Player of the Year awards at the end of his first season with the club.
