This is a derby match that is always fierce and the tension of the game is different so of course this match will be quite difficult to predict, overall Real Madrid's strength is indeed slightly better but it is true that Atletico Madrid who play at home are not easy to beat and statistics have shown so.
So I don't favor one of them in this match because I think both still have the same percentage to be able to win the match and I even think it is very likely that this match will end in a draw.
Yes, in principle Real Madrid will have a tougher time this matchday than Barcelona, who play Osasuna in Pamplona and although they have not had a bad start to the league, they will be an easy opponent to beat.
On the other hand, the derby is usually more complicated for Madrid and even more so playing at Atletico's ground. To this we could add the pressure that Madrid are in second place and if they lose and Barcelona win they will start to take a considerable lead, in addition to the fact that Atletico would pass them on points (Madrid) and other teams, depending on the results of the day, could also do so.
Barcelona is advantaged in week 8, they will visit Osasuna's home, Hansi Flick's team must be able to take advantage of this moment to get full points to be more comfortable in the standings.
On the other hand, their rivals will play a tough match, yes if Real Madrid loses, it will be increasingly difficult to approach Barcelona's points and their position will be shifted by ATM,
This derby does not benefit Real Madrid because they have to visit ATM's headquarters, a match that will present drama, although both teams have the same opportunities but it will be difficult to predict, Ancelotti's troops must really perform well in this match, there must be no mistakes at all.
