The 25-year-old joined Chelsea for a reported fee of around £46 million last summer but after failing to establish himself as a regular, was shipped out to AC Milan on loan for the second half of the season.
Chelsea are now looking to sell Felix as soon as possible, with former club Benfica looking like the most likely destination.
According to Portuguese outlet Record, Benfica are hoping to secure his services this week for approximately €20-25m, although A Bola report Chelsea are holding out for a bigger fee.
Felix is one of several players Chelsea are looking to sell this summer, with the likes of Raheem Sterling, Ben Chilwell, and Axel Disasi, among others, also expected to leave.
