Napoli is reportedly looking to sign yet another player from Manchester United in the January transfer window. This time, their target is 17-year-old midfielder Lukas Mainoo. Mainoo has been an outcast at Old Trafford, struggling to break into the first team. Napoli's interest in the young player is not surprising, given their history of scouting and signing talented youngsters from the Premier League. The Italian club has a reputation for developing young players and giving them a chance to shine.

Mainoo's potential move to Napoli would be the third time this season that Manchester United has seen one of their young players depart for Serie A. Earlier in the season, Napoli signed 20-year-old goalkeeper Alex Sandro from United's youth academy. In August, the club also signed 21-year-old winger Anthony Elanga from United's first team.

The transfer window is expected to be busy in January, with many clubs looking to strengthen their squads ahead of the second half of the season. Napoli, in particular, is expected to be active in the market, with several positions in need of reinforcements. Mainoo's potential signing would be a significant coup for the Italian club, given his potential and the fact that he is still just 17 years old.

Manchester United, on the other hand, is expected to receive a significant transfer fee for Mainoo, given his potential and the fact that he was signed from a rival club. The sale of Mainoo would be a significant boost to United's finances, which have been impacted by the COVID-19 pandemic.
