The 23-year-old winger is on the verge of moving to La Liga on a permanent deal following his season-long loan at Rayo Vallecano
Gael Kakuta will undergo a medical with Sevilla on Thursday ahead of his proposed move from Chelsea.
The 23-year-old is out of contract this summer but Goal understands Chelsea will receive around 4 million euros in compensation because the winger is under 24.
Kakuta joined Chelsea in 2007 but has made only 12 senior first-team appearances, including one Premier League start which lasted just 45 minutes against Aston Villa in 2010.
