Aston Villa have signed midfielder Glenn Whelan from Stoke City for £1m and experienced defender Chris Samba on a free transfer.
Whelan, 33, who has been capped 81 times by the Republic of Ireland, has signed a two-year contract.
Samba, also 33, was a free agent after leaving Greek side Panathinaikos in January and has signed a one-year deal after spending pre-season with Villa.
He previously spent five years with Blackburn and also had a spell at QPR.
Whelan made 336 appearances for Stoke after arriving from Sheffield Wednesday for £500,000 in January 2008.
He scored six goals, including a 90th-minute equaliser at Villa Park in 2009.
Samba scored 18 goals in 186 appearances for Blackburn after joining from Hertha Berlin for a bargain £450,000 in January 2007.
But he spent only six months with QPR, rejoining Anzhi Makhachkala for £12m in July 2013 after signing from the Russian side for £12.5m the previous January.
