In essence, Bellingham presence in the Real Madrid squad has clearly had a positive impact on Real Madrid performance and match results so far. Because the fact is also, that Bellingham is also at the top of the La Liga top scorer list at this moment. Therefore, Real Madrid is still in very good form so far because I think, this improvement in Real Madrid's performance is also proof that Real Madrid recruited the right players like Bellingham.
But even so, I personally do not consider Barcelona weak. Because after all, Barcelona also did not get a defeat so far and yes, Barcelona only got one draw in the initial match. With results like that, then of course the competition between Real Madrid and Barcelona this season will remain fierce. Because Barcelona also still has a promising performance, of course, to be able to compete strongly in the race for the La Liga title this season.
The Bellingham transfer was a good transfer, but sometimes things work out so well that luck was on Bellingham's side, too.
He scored four goals so far I believe and there is nothing to be said against his performance since he plays an offensive position and delivers, but seriously it would not be realistic to think that he can keep going at this level in terms of scoring. Real Madrid has had a close games as well against Celta, which could also have been a draw on a bad day.
It's more realistic to see where everything is at after maybe ten games or so. If it turns out that Bellingham turns into a La Liga top scorer over a longer period of time, I would say that Real Madrid has the strongest offense with Vinicius Junior and Rodrygo and then Bellingham. In my opinion it would be stronger than that of Barcelona.
