His personal issue has already affected the club's performance because he is human and will have divided mind. The match is in two days' time, and we shall all know which of these two clubs will win the match. Madrid has a weak defense but not as porous as that of City, which means that the attackers are the ones to decide who wins the game. I will bet on Madrid because their attackers are very sharp and sound.
What are our presuppositions for this clash? Both parties have history and unsettled scores. Firstly we start with Manchester City, they're the hosts at Etihad Stadium. This is their ground and they will always keen on grabbing three points at home compared to the visitors, Real Madrid. They're eligible and ready for every possible threats from Citizens, we know how suspense this game will be for both the fans and the players. Pep Guardiola is preparing his formation against his next oppositions. This is crucial for his meeting with Carlo Ancelotti, we know these geniuses have been prominent in UEFA Champions league, we know their records when it comes to important games like this.
Both teams have suffered from countable defeats this season, and I see it's not helpful for them. City have suffered from injury blow on their main players, thereby forcing Pep Guardiola go seek for direct means of adaptation of new pattern, the exact same thing apply to Los Blancos. You can see they're not that different but very much alike.
