Real Madrid have already progressed in La Liga and now only need to do a little better in the Champions League.
Real Madrid have been unlucky in the Champions League games. I believe that these defeats are related to injuries and the fact that at that time Mbappe had not yet managed to adapt well to the team. But now the situation is very different, Mbappe is already playing well. Tomorrow Real Madrid will be without: Vinicius, Dani Carvajal, Eder Militao and Eduardo Camavinga.
Real Madrid's game against Brest will be tough because Brest has been a strong opponent this season most especially in the Champion League match, Brest is ahead of Real Madrid in the Champion League table with 1 point and both teams will be fighting for get the opportunity to make it to top 8, although it will be very difficult for both teams to qualify to top 9 of the league table but anything can happen as football concern, Brest is playing at home and that will make them feel good and play well against Real Madrid, so Real Madrid need to get prepared for the match.
Real Madrid can win the match but it is not going to be easy for them, If Carlo Ancelotti wants to win this match he needs to Bench Mendy and Lucas to make the defensive position look strong, Modric and Cebalos should also start the match with Bellingham and Valverde should play as Right back, if Ancelotti wants Tchoumeni should start the match I think he should play him as a midfield, not a defensive player because he is not good as a defender, The reason why I prefer Ancelotti should make some change is that Real Madrid is not that strong when it comes to defense.
