Newcastle is beginning to strengthen their squad ahead of their return to the Champions League next season after a superb campaign the last time out and could shop at Chelsea.
The Blues have several deadwood in their squad now after Mauricio Pochettino met arguably the biggest squad in England when he was named their manager.
Several players will leave, and Newcastle is looking to get a piece of that before the transfer window closes. They have now made Marc Cucurella a target, The Sun reports.
The Spaniard only moved to Stamford Bridge from Brighton last season in a deal worth around £62m, but his first season at the club was poor, as was the case with most players they signed.
Pochettino could offload him, and Newcastle United are now looking to add him to their squad as they chase a new left-back to improve their options.
The Magpies have held a long-standing interest in Kieran Tierney, but they might struggle to convince the Arsenal man to join them as the Gunners are doing well.
However, Cucurella is seen as an easy target for them to add to their squad for the right fee if the Blues will accept around £30m or less for his signature, as no one will invest a heavy sum to sign him.
