Chelsea are reportedly stepping up their pursuit of Rayo Vallecano left-back Pep Chavarria, with the Blues said to have lodged an improved offer worth around €15m for the young Spaniard, according to English Premier League Index.

The report suggests Chelsea have been tracking Chavarria for some time but have now returned with a sweetened bid as they look to strengthen their options at left-back. Enzo Maresca's side are understood to view the position as an area requiring reinforcement, and Chavarria has emerged as a key target amid the club's broader summer recruitment plans.

While the figures indicate Chelsea's determination to get a deal over the line, there's no confirmation yet that Rayo Vallecano are ready to accept the revised proposal. As it stands, this remains a live negotiation rather than a completed transfer, with the Spanish club's response to the latest offer still awaited before any move can be finalised.
