Manchester United's hierarchy are concerned about hiring Antonio Conte as they feel his style is "too similar" to Jose Mourinho's, according to the UK Telegraph.
Conte is believed to be keen on replacing Ole Gunnar Solskjaer at Old Trafford.
The former Chelsea and Inter Milan boss is currently out of work.
United are considering Solskjaer's future following a disastrous 5-0 defeat at home to Liverpool on Sunday.
Solskjaer indicated after the game that he wants to continue in the role, but members of United's squad now have major reservations over his tactical nous and decisions regarding team selection.
Conte is among the frontrunners to replace Solskjaer, but United's hierarchy are "wary" of his man-management and fear his methods are "too similar" to that of Mourinho.
Solskjaer replaced Mourinho after the Portuguese was sacked in December 2018.
In the months leading up to his exit from Old Trafford, Mourinho was criticized for how he handled several United players, ultimately failing to win over the dressing room with his approach.
During his time at Chelsea, Conte was accused of similar failings during his second season, with many players unhappy with his hardline methods.
Conte also regularly called out Chelsea's hierarchy in his final season, accusing them of lacking ambition in the transfer market.
Last season, Conte also publicly showed his frustrations towards Inter's hierarchy, despite guiding the team to success in Serie A.
Conte went on to leave just three weeks after their title win.
