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.
There are always a lot of interesting things if these two clubs meet. But I heard about Bellingham possibly missing out through injury. Bellingham became an important player during his time with Madrid, he made half of Real Madrid's total goals. So losing Bellingham in this game will make Real A little difficult. But other news writes that Vinicius, who suffered a hamstring injury with predictions until October, has recovered. It is likely that Vinicius can play in this match.
So far there has been no further confirmation from Madrid regarding Bellingham illness. I read on the club official website that Bellingham did not participate in the training session because he had a stomach ache. The good news is that Vinicius Jr and Arda Guler have joined the training session, this is good news for Ancelotti. If Bellingham is really absent, this will really give Ancelotti a headache, because Bellingham has been a key player so far. However, I have a feeling that Bellingham will be able to play in the derby match against Atletico, because the England national team player is not injured but only experienced stomach ache.
So far, Madrid can still win even though they are not supported by a number of important players Thibaut Courtois, Arda Guler, Eder Militao and Vinicius Jr. I predict that the derby match will be won by Los Blancos, even though it is a narrow victory.
