The 28-year-old Australian attacker joined Villa from Dutch club AZ Alkmaar after a decade in the Netherlands.

Holman, who scored seven goals and provided 15 assists for AZ last term, said he was determined to prove his worth at Villa.

"I think I can contribute a lot to the team. I want to show what I'm worth," Holman told the club's website.

He added: "I can't wait to get involved, meet the lads and get stuck into life at Villa. The first time stepping out at Villa Park will be a big moment, also. It will be a great feeling. It's a great stadium and I can't wait."

The Sydney-born attacking midfielder, who previously made no secret of his desire to move to England, said the transfer was a "dream come true".

"I am so happy to be here. It's a dream come true to be a Premier League player. To have that opportunity at a club with the history and tradition of Villa is fantastic," Holman said.

"I am so excited and can't wait to get started. There are big names here. I was more than aware of the quality players at Villa, even though I've obviously come from the Eredivisie in Holland.

"Just look at Darren Bent, who's a top-quality goalscorer and a proven England international. I want to meet up and play with the lads. It's certainly exciting times."
