Atletico Madrid is a strong team, they can really compete for the La Liga title. If they can consistently collect a lots of points then the title will be in their hands, but there will be a tough job for them against Real Madrid in this month. If Atletico Madrid can win and secure the three points, then they have the opportunity to overtake Real Madrid. In the match vs Real Madrid, Atletico Madrid have the advantage because currently Real Madrid is missing their key player.
Real Madrid next opponent is Real Sociedad in La Liga, while in the UCL group phase Ancelotti squad will face Union Berlin. Atletico will face Valencia in La Liga, and in the UCL Group Phase Diego Simeone squad will face Lazio. It is clear that Atletico will have a slightly tough match before meeting their city rivals, while Real Madrid will have a slightly easier match.
This derby will be presented in the sixth week, victory in the fifth week of La Liga and the UCL Group Phase will be capital for both of them to appear more confident. I think Real Madrid will be able to beat Atletico at their home ground, because Rodrygo is back from injury.
