Napoli coach Rino Gattuso admits he'll be disappointed if Kalidou Koulibaly is sold.

The 29-year-old has been linked with moves to Manchester City and Manchester United but the Serie A club are believed to want over £70million for his services.

Gattuso said: “He's a serious guy.

"If he'll leave I'll be sad because Koulibaly is a top player... it's a difficult moment in football and you've to consider important bids.

"But if he'll stay, I'll be happy."

Gattuso was speaking after Napoli's opening day victory over Parma.
