Lyon have revealed what Chelsea must do to sign Bradley Barcola this summer, according to a report on Metro.

The French side have reportedly told Chelsea that they want cash plus a player swap in order to sell Bradley Barcola this summer.

Chelsea have stepped up their interest in signing 20–year–old Barcola after missing out on Crystal Palace star Michael Olise.

The Blues had also been considering a move for Nottingham Forest’s Brennan Johnson but have now withdrawn their interest and are focusing on Barcola.

Chelsea head coach Mauricio Pochettino wants to bring in at least one more attacking player before the summer transfer window closes.

Barcola can operate as a forward or right winger and has spent his entire senior career at Lyon, where he registered seven goals and 10 assists last season.

French champions Paris Saint-Germain are also interested in signing Barcola.
