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.
