The Frenchman's £52m move to SW6 in 2023 has proved unsuccessful so far, with the former RB Leipzig man managing only six Prem goals in his 38 league appearances for the Chelsea.
Lopez has also struggled for consistent minutes at Barcelona, falling behind the likes of Dani Olmo, Raphinha and Gavi in the pecking order for the Catalan giants.
However, he is still understood to be considered a crucial part of Barcelona's future - picking up 18 goal contributions across all competitions this season.
It's claimed that the only way Barcelona would let Lopez go would be if the Spain star pushed for an exit himself in search of more regular minutes.
Lopez will have one eye on making Luis de la Fuente's Spain squad for next summer's World Cup, something he will have to be playing regularly to achieve.
