Chelsea have added Napoli defender Kalidou Koulibaly to their summer shopping list.
The Senegal international is about to enter the final year of his contract and is on Barcelona's radar.
However, AS says Chelsea are also interested.
The Blues could ferry away the defender from Napoli for £30m.
President Aurelio De Laurentiis admitted last month that, whilst Napoli would like Koulibaly to remain at the club, they cannot force his decision.
"He is a symbol of Napoli, and if he wants to no longer be a symbol, he must decide," he said.
"We must decide. we want Koulibaly to stay, but people can't be forced to stay. Everyone has their own dignity and needs. We respect everyone."
