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.
I think him being great at national level was a good proof without a doubt, but also the fact that Real is not "forced" to use him every game is a big advantage as well. He is young and they could still have tchouameni, valverde, camavinga and more veterans like Kroos and Modric, all midfield and all could replace Jude at any given moment.
This is why Jude will have to fight for that jersey, and that means he will have to show his best. At Dortmund he almost won the title over Bayern, lost just at the last game, would have been so sweet to leave after finally getting a title. Showing what he was capable of, and that's why I believe that it is going to be pretty special for him to play at Madrid, he will be a great player without a doubt.
