Millwall have signed Australia international defender Kevin Muscat on a free transfer from Rangers.
Muscat only spent a season at Ibrox
Muscat, capped 43 times by the Socceroos, will join his fourth British club after starting his career with South Melbourne.
The abrasive Australian joined Crystal Palace in 1996 before moving onto Wolves, and then joined Rangers in July last year.
But after 25 appearances for the Scottish champions he has returned south of the border on a three-year deal.
Lions boss Mark McGhee said: "I'm looking to improve our defensive record, which is already excellent, and also put a bit of emphasis on the quality of our play going forward, including the full-backs."
Muscat could go straight into the side to face former club Palace on Saturday.
