Jude Bellingham is Real Madrid's best signing this season, but everyone should be aware that he is not a striker even though he has scored 8 goals in 8 appearances in La Liga. Ancelotti emphasized that supporters should not expect too much from his performance to win every match, even if one day he doesn't score a goal, they shouldn't blame Bellingham.
He is talented and he already proved it in Dortmund as well as with England in World Cup 2022. However I really believe even Real Madrid did not expect Jude to score so many goals like this. He is their best scorer now and his stats is more similar to a striker rather than a midfielder. It's lucky for Real Madrid as in a season they have problems with their strikers (Benzema left, Joselu has yet replaced Benzema too well), Jude appears as a very goal productive attacking midfielder for them.
Real Madrid is a team that I think is not only about Bellingham. They play for the benefit of the team rather than personal interests, so they should not rely on one player even though they can provide something different throughout the match. I hope Bellingham is able to maintain his best form this season, and enable Real Madrid to win the title at the end of the season.
They still have many star players in their team and you are right, their strength is not only from Jude Bellingham. If opponents focus too much on Jude Bellingham, Real Madrid can shift their attacking power to other players and their opponents will be beaten by other players, not by Jude Bellingham. To win a title, to beat Barcelona and win La Liga, they will need to adjust their tactics and avoid being dependent too much on Jude.
