A move for Cucurella will please Chelsea boss Thomas Tuchel, who has grown frustrated by the lack of activity in the transfer market this summer. Tuchel’s squad needed plenty of additions at the end of last season.
So far, only Raheem Sterling and Kalidou Koulibaly have arrived at Stamford Bridge from a first-team perspective. Chelsea will crack on with further deals in the coming weeks as they mount a challenge for the Premier League title.
Wesley Fofana, Frenkie de Jong, Benjamin Sesko and Denzel Dumfries are all on their radar as they look to do more deals before the window closes. Leicester are adamant that centre-back Fofana will not be sold.
But the Foxes need to balance their books before they can complete their own business. They are the only Premier League club yet to make a senior outfield addition.
Meanwhile, Chelsea could beat Manchester United to both Barcelona midfielder De Jong and RB Salzburg striker Sesko. Inter Milan wing-back Dumfries is also of interest.
