Tomas Rogic's move from Central Coast Mariners to Celtic will become official once he receives his work permit.
The 20-year old Australian attacking midfielder has signed a four-and-a-half-year deal with the Hoops following a successful trial with the Glasgow giants but a visa needs to be cleared before he becomes an official part of the squad.
"Celtic are delighted to announce the signing of Australian Tom Rogic on a four-and-a-half year deal subject to a work permit," read a club statement.
"The Club can confirm an application will be made to the appropriate authorities in the next couple of days."
