According to the Italian media outlets, Manchester United reportedly had a €90m (£83m) bid for Napoli centre-back Kalidou Koulibaly rejected in the latter stages of the English transfer window.
The Red Devils were strongly linked with a move for Koulibaly before eventually agreeing to sign Harry Maguire from Leicester City ahead of the start of the 2019-20 campaign.
The English giants broke the transfer record for a defender when they paid £80m to bring the England international to Old Trafford.
As per the Corriere dello Sport, United actually submitted a €90m (£83m) bid for Koulibaly before the transfer window slammed shut. Napoli, though, signalled that they would not sell at that price.
The 28-year-old has made over 200 appearances for his Italian club since a 2014 switch from Genk.
Real Madrid and Barcelona have also been credited with an interest in the defender, who could still leave Naples for La Liga before the Spanish transfer window closes at the start of September.
Meanwhile, Inter Milan have reportedly struck an agreement with Manchester United to bring unwanted defender Matteo Darmian to the San Siro on a free transfer.
The Italian, who joined United in 2014, has only made 14 Premier League appearances over the last two campaigns at Old Trafford.
