Chelsea and Arsenal are tracking Napoli fullback Faouzi Ghoulam.

TMW says both London giants had scouts at the San Paulo for Saturday's shock defeat to Atalanta.

And the subject of their attention was Ghoulam.

Experienced agent Vincenzo Morabito expects the fullback to leave this summer, though for Lorenz Insigne, also a target for Arsenal, he sees him staying.

"For Ghoulam I think we will see him leave, while Insigne is a different matter," he told Radio Crc.
