Real Madrid will face Juventus in the round of 16, and it looks like Juventus will be a tough opponent compared to their previous opponents, so it will be interesting to see whether Xabi Alonso will continue to play with 3 defenders or perhaps he will experiment again using a different strategy.
Real Madrid won't find it difficult in the round of 16 match against Juventus because for the fact that Juventus lost to Manchester City in their last game, Real Madrid must have identified their weakness which they will capitalize on that aspect and make sure they use it against them. Juventus used to have a very solid defense but after Manchester City scored 5 goals in their last meeting, i saw the porosity in their defense which means if they must repel the attack of Real Madrid then they must make sure they focus more on their defense region or play a defensive formation, that is the only way to make the game difficult for Real Madrid. These are the early matches of Xabi Alonso, he won't gamble any chance to reach the FIFA club world cup final and winning Juventus shouldn't be what will give him sleepless nights.
Juventus's poor performance against Manchester City in their last match is not something to be taken lightly. Real Madrid will be favourites against Juventus, but the outcome of the match could go either way at any time, so Real Madrid will have to be on their toes and not give Juventus any chance. Real Madrid's performance in the last match of the Club World Cup suggests that we may soon see the old Real Madrid, who are very good at counter-attacking. Best wishes to Real Madrid for their match against Juventus.
