Ancelotti was announced starting line up for champion league final that there were several name who has rarely played in this season like Bale and Hazard although these players probably will play as substitute players but Liverpool have to be careful with them especially if they are in good form because not impossible they will appears as super subs especially Bale that he is the player who shattered Liverpool's dreams to get the trophy in the previous final on 2018
Even though Bale and Hazard are in the lineup I don't think it's a threat Liverpool's capacity is unquestionable other than that Bale and Hazard have played in the EPL so it's nothing new. I think Ancelotti has other plans by including Bale and Hazard he wants to disrupt Liverpool's strategy or break Liverpool's concentration on some of the main players.
I agree with you on this, Ancelotti will always want to disrupt the plains of Kloop by bringing the news of Hazard and Bale who have been sideline injury players, but we have to be more careful with the two players especially Bale because he is a great player full of energy, pace, and experience in the Champions League, Liverpool shouldn't forget Vinicous J and Benzema because they are the stars of the game. Liverpool has a solid team too and am sure they are well prepared and ready to battle with Madrid, Mo Salah, Dias, and Mane should not be underestimated cause they are full of surprises especially in front of the goal post.
