Aston Villa recently completed the signing of Emiliano Buendia for a club-record fee from Norwich City.
The Villa manager is unimpressed with Morgan Sanson’s performances, and Douglas Luiz’s long term future is also unclear.
Ward-Prowse has been a reliable Premier League midfielder in recent years, and he could prove to be a quality addition to Smith’s squad.
The 26-year-old is an excellent passer and lethal from set-pieces. His arrival would add a new dimension to Villa’s attack.
The West Midlands club have an excellent dribbler in Jack Grealish, who tends to win numerous free-kicks, and Ward-Prowse could benefit.
He bagged nine goals and seven assists for Southampton in all competitions last season and would be a useful option for Villa.
The Southampton midfielder has four years left to run on his contract, and Villa will probably have to pay a premium to secure his services this summer.
