Felix's career trajectory saw a steep decline after his €126m (£110m/$147m) move to Atletico Madrid. Struggling for consistency, he failed to establish himself at Atletico, Chelsea, Barcelona and AC Milan, despite flashes of talent. Benfica were keen for a homecoming, which Felix himself had publicly stated he wanted, but the Eagles could not match Chelsea's asking price or his salary. Ultimately, Al-Nassr’s financial clout, along with Ronaldo’s active involvement - reportedly persuading his compatriot to sign in order to build national team chemistry ahead of the 2026 World Cup - quickly changed the course of negotiations. Chelsea are expected to use proceeds from the sale to pursue further reinforcements this window.
