Chelsea will discuss the structure of a £30million deal for Villarreal forward Nicolas Jackson this week.
Talks have accelerated as Saudi Arabian club Al Nassr push to sign Chelsea winger Hakim Ziyech and Arsenal continue to negotiate for Kai Havertz, with Bayern Munich in the wings.
Jackson, who has a £30m release clause, has interest from a number of clubs including Aston Villa and Bournemouth, who tried to sign him in January only for a hamstring injury to scupper the move.
However, he is set on Chelsea with personal terms already in place and the club will look to pay in instalments.
Though Jackson returned to fitness and made a significant impact on the second half of the season, scoring nine goals, Chelsea will study his medical before a deal is agreed.

Manchester United are expected to make an improved £50m offer for Mason Mount this week.
