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.
