Roy Keane is relishing the challenge of combining the Barclays Premier League with international football after being confirmed as Aston Villa's new assistant manager.

The 42-year-old, who is also No.2 to Republic of Ireland manager Martin O'Neill, will work alongside Paul Lambert as the pair attempt to revive Villa's fortunes after a difficult last campaign.

"I am relishing the prospect of linking up with Paul Lambert and combining both roles to the full advantage of both Villa and Ireland," said Keane.

Lambert's staff was ripped apart earlier this year when his assistant Ian Culverhouse and football operations manager Gary Karsa were suspended and then sacked for unspecified disciplinary reasons.
