The Championship new boys have reportedly made a £14.5 million offer for the 19-year-old Guinean, but they may face strong competition for his signature from the likes of Napoli and Roma.
Diawara, 19, joined Bologna from Italian fourth-tier side San Marino last summer for a reported £420,000 fee and went on to make 34 appearances for the club during his first season in Serie A, helping them secure a 14th-place finish with some standout performances.
The highly-rated Guinean, who first moved to Italy from his native country in 2014, has since been linked with a host of top teams across Europe and recent rumours have even named Juventus as a possible destination in the wake of Paul Pogba's move to Manchester United [h/t Gazzetta dello Sport].
The likes of Bayern Munich, Chelsea and Manchester City have also reportedly been monitoring the tough-tackling middle man since his Serie A breakthrough [h/t Sky Sports], while he had looked close to joining Valencia earlier this summer before the deal collapsed over Bologna’s financial demands.
He is still expected to leave I Rossoblu in the coming weeks, however, and it is now being suggested that Villa are one of several clubs in the mix for his high-priced signature.
According to Di Marzio, the claret and blues have made a €17 million [£14.5 million] bid for Diawara that meets Bologna’s asking price and are now waiting to hear back from the teenager's camp as he considers his options.
Napoli and Roma are also said to be weighing up bids that could scupper the Championship club’s plans, but neither side is understood to have made a formal approach at this point.
Diawara would reportedly prefer to stay in Italy, but he is also believed to be largely open to a move to England, even if it would mean spending at least one season in the second tier.
It would certainly be a real statement of intent by Villa’s new regime if they ultimately manage to win the race for his services, but it looks like there could still be a few more twists and turns to come in this supposed transfer saga.
