Chelsea moving for Lazio forward Keita Balde Diao.
La Repubblica says Antonio Conte fancies a swoop for Keita.
The Senegal international has entered the final year of his contract and is refusing to sign an extension.
Chelsea could launch an offer worth up to £17.7m (€20m).
Lazio president Claudio Lotito, however, is holding out for up to £26.5m (€30m).
