Manchester United manager Ole Gunnar Solskjaer has reportedly sent a scout that will see Napoli defender Kalidou Koulibaly facing a world record in the summer.

According to The Sun, who reports that Solskjaer has sent his top scout Jim Lawlor to watch Napoli's 1-0 win at Napoli's A-team.

Lawlor is said to be impressed by the Senegalese international, but if United wanted to buy him, they would have to set a defender-of-the-world record higher than the £ 75m Liverpool had paid for Virgil van Dijk.

The report states that United Koulibaly has made it its "number one target" this summer and is ready to pay £ 90 million to sign the 27-year-old, who has been in Napoli since 2014.

However, Kolibaly is quoted by Rai Sport as saying, "I'm flattered and it's gratifying to know, but I'm just focusing on Napoli and proving what I can do on the field.

"In Napoli there is a lot of motivation for me, we want to prove that we are at the highest level and I want to continue to improve here."

Meanwhile, United is reportedly confident that David De Gea will sign a new £ 90m contract that would make him the highest paid player in England.

The Sunday Times says United are ready to ensure that De Gea stays with United by offering a basic compensation package that is the biggest in English football, and he is confident that he will sign.

The Spaniard was in the last few years repeatedly the leader of United and the club wants to bind the 28-year-olds with a long-term contract.
