Albert Adomah goes back to the English Championship on Transfer Deadline Day.
The 28-year-old joins international teammate Jordan Ayew who joined the Championship club from FC Lorient at the start of last season.
Adomah helped Middlesbrough qualify from the English Championship to the English Premier League last season.
The Ghana international has played one game out of the three opening matches for Middlesbrough in their return to English top flight.
Aston Villa who were relegated from the Premier League last season are looking to strengthen their squad for a quick return next season.
The club who sacked two managers last season appointed former Chelsea coach Roberto Di Matteo to take charge of their Championship season after the drop.
Owner of Aston Villa Tony Xia welcomed the Black Stars player with a photo tweet captioned:
“Welcome to Villa Adomah! #UTV@AVFCOfficial”
