Leeds United are in talks with Feyenoord over a deal for Colombia international Luis Sinisterra.
The 23-year-old winger scored 23 goals last season and has emerged as Leeds' prime target to replace Raphinha.
Chelsea agreed a fee of £55m plus add-ons for Brazilian wideman Raphinha last week but Barcelona, the player's preferred destination, countered with an offer on Thursday.
Leeds have still to accept that offer as it is understood to amount to £51m paid in instalments of £17.2m.
And Feyenoord want a club-record fee of around £23million for Sinisterra, who also has interest from Everton.
