Manchester City are to open the bidding for wing-back Marc Cucurella but Brighton want around £50m.
The 23-year-old is open to joining City but the deal will hinge on Brighton’s valuation.
City are expected to propose up to £40m including add-ons and are prepared to consider alternatives if Brighton hold-out for a greater fee. Chelsea are monitoring developments too.
Current City full-back Oleksandr Zinchenko has attracted interest from Arsenal, Everton and West Ham, and the Premier League champions could look to replace him with Cucurella.
Meanwhile, from Chelsea's perspective, they may view Cucurella as the ideal player to provide competition for Ben Chilwell next term, with the England international only recently returning from a lengthy spell on the sidelines with a serious knee injury.
