I think Real Madrid was the worse team and they didn't win the championship. Barcelona played very passionately and concentrated last year. The better side in El Classicos was Barcelona. When this is the case, it is not correct to accuse a single player. Real Madrid have to be better this year and they should definitely get a striker for that. Joselu may not be able to handle this region alone.
Of course, Joselu's arrival has high hopes of replacing Benzema. He can eliminate dependence on Benzema. Looking at some training sessions I was quite happy with his performance. Guler's arrival also makes a sense of optimism for the new season. He showed his quality as a player of hope for the future. With his young age and incredible ability, I think there is certainly confidence to play more that Anceloti has to give Guler. The hope is that no transfer fails due to injury. Such is the case of Hazard.
Hazard is a transfer that failed miserably, because Hazard was brought in at a very high price but Hazard did not have any contribution to Real Madrid. So, even if Joselu doesn't really contribute well, it won't be a problem because Joselu is an old player anyway. So yes, we cannot expect the same performance and contribution between Benzema and Joselu, because of course they have different skills and power. But anyway, at least Real Madrid have a good movement to be able to regenerate the team for the long term, because the young players that Real Madrid currently have are considered to have great potential and quality from time to time.
