Real Madrid is in very high form. They have won all 6 recent matches. I'm impressed with Real Madrid's playing style this season. They are really strong. They still played a formidable attack, with Jude Bellingham shining with 5 goals. But in attack, it is likely that striker Vinicius will continue to be absent.
As for Atletico, They will welcome the return of Koke, De Paul, and Memphis Depay. The last-minute draw in the Champions League match was considered unlucky due to the excellent situation of the Lazio goalkeeper. However, in general, they are playing very well, so this match has a high possibility of a draw.
So far Realmadrid made the best signings of the summer in person of Jude Bellingham and since his arrival into the team he's been the most outstanding player and lead them to victory several, for his age he's very impressive and has become the most important player in Madrid currently, the attacking line of the team is not really very solid due to the departure of Karim Benzema and the injury of Vinicius Jnr but the presence of Jude Bellingham has made it something to worry less about.
Realmadrid are the favourites to win the match, of course it's not going to be easy due to Athletico's defense which might take Madrid a while to figure how to get past them but I believe Madrid would perform better and dominate more because they've got a better performance than Athletico and even better players they could rely on to defeat Athletico.
