Remi Garde looking to strengthen
Villa are eyeing up four new signings in the January transfer window, according to reports.
Defenders Lamine Kone, 27, from French club Lorient and 24-year-old Tom Lees from Sheffield Wednesday have both been linked with the club.
Mainz's 22-year-old goalkeeper Loris Karius is a target and 19-year-old midfielder Samuel Bastian is rumoured to be of interest.
Villa are also the bookies' favourites at 9/2 to sign striker Charlie Austin from QPR in January.
