Liverpool are also rumoured with Felix actually. It depends on Salah to leave for Saudi Arabia though. If this happens Liverpool can also intervene the deal. Felix's priority is Barcelona and it will be other European teams if possible. If none of them happens then Saudi Arabia will be his new target most probably.
Felix had good performances before but currently, his situation is not good at Atletico Madrid because this player showed his interest in Barcelona and made the Atletico fans mad, I think it's time for Felix to move to another team, and since Barcelona can't hire this player because of the financial issues he can consider even returning to Chelsea.
This is what I expected of Pouchettino a long time ago, I mean why would he even think of leaving out a player who was the one of the most outstanding player for the club last season, even with their poor performance, i was thinking that when he came inro the club one of the firsr things he would had done after offloading the players he felt he couldn’t work with was bringing back João Félix who was on a loan with them, his deal won't have been tough, because the player is currently not very intrested in working with Atletico Madrid's coach Simeone and would glady accept to move back to Chelsea and would had even helped them in their previous matches.
Well if salah ends up moving out of Liverpool, Felix would be a very good replacement, cause he's skillful, has pace and can control the ball with speed from the flank than Salah the português even have a good crossing ability.
