Manchester United has set the world record for Kalidou Koulibaly & # 39;

The Manchester United manager, Ole Gunnar Solskjaer, would send a scout to see Napoli defender Kalidou Koulibaly ahead of the world record offer in the summer.

This is according to The Sun, who reports that Solskjaer sent his top scout Jim Lawlor to watch the Naples midfield in a 0-0 draw in Serie A last Saturday in Fiorentina.

Lawlor said he was impressed by the international Senegalese, but if United wanted to buy it he would have to produce a world record for a defender that exceeds 75 million pounds that Liverpool paid Southampton for Virgil van Dijk.

The report says the United States has made Koulibaly their "number one goal". in the summer, and are willing to pay £ 90 million to sign the 27 year old, who has been in Naples since 2014.

However, Kolibaly is quoted by Rai Sport: "I'm flattered and I'm glad to know, but I focus only on Napoli and trying what I can do on the field.

"There are many motivations for me at Napoli, we want to show that we are at the highest level and I want to keep improving here".

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

The Sunday Times says that United is willing to ensure that De Gea remains in United by offering a basic payment package that would be the largest of English football, and will feel confident that it will sign.

The Spaniard has always been the best player of United in recent years, and the club wants to tie the 28 year old with a long-term contract.
