Benfica Chairman Rui Costa was interviewed a few days ago and talked about the team missing Felix this summer.
Rui Costa said: "We had great expectations for Felix's return, and we also worked hard to make the deal."
"But it is impossible for us to compete with Saudi clubs. During the negotiations with Chelsea, Felix always wanted to return to Benfica until a offer from Saudi Arabia that he thought could not be rejected. I could not compete with the price code that Saudi Arabia offered for the players."
