As reported by AS, the Portuguese striker is "depressed" and feels deceived by the president of the "royal club" Florentino Perez. He promised Ronaldo that he would re-sign a contract with him on improved terms, but he did not keep his word.
It is reported that Peres promised Ronaldo updated contract after winning the Champions League 2016/17, but this did not happen, although the player himself hinted at it.
Now Ronaldo is going to leave the club and return to Manchester United. This striker even told several teammates.
Note that Ronaldo is not included in the list of the world's highest paid players and his salary is significantly less than that received by Leo Messi in Barcelona, ??as well as Neimar in PSG.
