Chelsea are in talks with Villarreal over the signing of Senegal forward, Nicolas Jackson.
It is thought Chelsea are prepared to meet the €35m (£29.8m) release clause with discussions centred on the structure of payments and performance-based incentives.
Informal talks with Jackson’s representatives have been positive and personal terms are not expected to be a problem if and when a deal can be struck.
Born in The Gambia and raised in Senegal, Jackson is one of a number of forwards Chelsea are looking at.
The 21-year-old was close to joining Bournemouth in January, but a hamstring injury scuppered the move.
