Adelaide United are set to add midfield depth to their A-League squad with the impending signing of Socceroos midfielder James Holland.

Fox Sports journalist Daniel Garb tweeted the deal on Tuesday morning, after the A-League champions had reportedly been in the hunt for Holland for weeks.

The 27-year-old was released from Bundesliga 2 club MSV Duisberg at the end of the past season, and Holland looks set to return to his home country and his second stint in the A-League.

Holland played for Newcastle Jets between 2007-2009 before moving to Europe where he plied his trade in Germany and the Netherlands.

The Socceroo made his national team debut in 2008 and has represented Australia 15 times over his career.
