Chelsea have allegedly made an offer to sign Napoli forward Dries Mertens, who is out of contract with the Italian outfit in the summer.
The Blues were credited with an interest in the Belgium international during the January transfer window, but Mertens ultimately remained at Napoli, where he has chalked up six goals and five assists in 21 league outings this term.
However, Frank Lampard's side have supposedly not given up in their pursuit of Mertens, but could face competition from Inter Milan to secure the striker's services.
Speaking to AreaNapoli, RAI journalist Paolo Paganini said: "Mertens leaving? If he went away, Napoli could place a double shot (sign two players, instead of the one attacker they're expected to).
"Inter and Chelsea have relaunched on [their attempts to sign] the Belgian, offering him a higher salary."
The 32-year-old has amassed 121 goals in 309 games across all competitions for Napoli since arriving from PSV in 2013.
