Napoli defender Kalidou Koulibaly reportedly remains as a summer transfer target for Manchester United.

While the centre-back has been frequently linked with a move to the Premier League, Napoli's asking price has always discouraged formal bids for the Senegal international.

However, their failure to qualify for next season's Champions League has effectively opened the door to lower bids being deemed acceptable during the summer window.

According to Gazzetta dello Sport, United are the most likely of the English clubs to make a serious effort to sign a player who turns 30 years old later this month.

Napoli president Aurelio de Laurentiis allegedly still wants to recoup at least £45m for Koulibaly, a significant reduction in his valuation after periods in excess of £80m.

Koulibaly has two years remaining on his contract, realistically putting Napoli in a position where they will have to be open to a compromise with any interested clubs. body check tags ::
