Maybe from the point of view of both Benzema and Joselu, they are not quite balanced because the experience and titles obtained are very different. But at least it's the most reasonable option for now for Real Madrid by bringing in Joselu. I think this will be a proving ground for Joselu with Real Madrid in the champions league next season and if he is fit to carry out his duties as a striker then Real Madrid will be very happy to make his move permanent.
Joselu is an average player and can not be compared to a star player like Benzema. He is even not comparable to Vinicius or Rodrygo with his quality. I believe Real Madrid have other plans to replace Benzema and Joselu is not a main play in those plans. Joselu can be helpful for Real Madrid when they need to use different squads and let their star players have some resting matches.
Jude Biellngham is good but Madrid already had excellent attacking Midfielders. Let's not react as if Bellingham alone will give Madrid the title less we get disappointed. German football isn't the same as Spanish.
Like another young English player, Jadon Sancho, left Dortmund to join Manchester United and after two seasons, still could not able to play well in Old Trafford. Three seasons ago, we talked that Sancho had a good growth than Foden but after that transfer, things changed and Foden have achieved more improvements and titles in the last two seasons.
In a team made of collective stars, factors like loss of form due to influence/ pressure from other players do affect performances. I wish this doesn't happen to him when he finally arrives. All we should pray for is that the team returns to it's formal understanding (team understanding) and winning mentality, cuz the analysis of Madrid's performance in last season shows a lack of confidence.
Changing from Bundesliga to La Liga will be big challenge. Playing in a club with many star players and with ambitious tasks from the club will be very challenging for Jude. Hope he will deal with it well and won't let his career destroyed in Madrid.
He played well in World Cup 2022 that is reason helps us to believe he is able to play well at high level like in La Liga. That World Cup performance gives hope but does not guarantee anything.
