Chelsea are losing ground in the race for Napoli's Bosman prospect Dries Mertens.
The Belgium international is reportedly a top target at Stamford Bridge but is also wanted by Inter Milan coach Antonio Conte.
Sky Italia says the 33-year-old would prioritise a move to the San Siro over a shot at the Premier League.
The claims follow the revelation that Chelsea manager Lampard has started following Mertens on Instagram, with the Chelsea manager's latest social media activity picked up by eagle-eyed fans, reports the Daily Express.
Lampard only follows 294 other users on the platform, despite boasting 4.1million followers himself.
