La Blaugrana have been heavily linked with a possible move for the Brazilian international after an eye-catching campaign from him at Elland Road.
With Leeds facing a potential final day relegation from the top flight, Barcelona are monitoring the situation with growing interest.
Raphinha is rumoured to have a relegation release clause in his contract, worth around €25m, and Barcelona are the current front runners to move for the former Rennes star.
However, as per reports from Mundo Deportivo, Chelsea are also keen on the 25-year-old, and they will rival Barcelona, if Leeds slip down to the Championship.
Chelsea are confident of securing a major buyout in the coming weeks, which would allow them to sign new players this summer, as the club look to recover from an underwhelming campaign in 2021/22.
