But if in the end he succeeds in getting them to put their egos aside and switch to a collective game then I think Madrid will really be very well protected in terms of goal productivity because indeed these two players are very solid individually but quite bad when placed together in one club so far.
This reminds me of the time when Zidane coached Real Madrid and they won the UCL three times in a row. Many said Zidane wasn't a genius coach, but he was lucky to coach Real Madrid alongside the prime Ronaldo. His passing tactics to Ronaldo became a topic of conversation on social media at the time. But what's not known is that teams with star players usually have big egos. Everyone wants to be the main character, and that's what can make a team with many star players fail. But Zidane was able to overcome each player's ego so they could play collectively. Real Madrid currently also has many star players, especially in the attack. Mbappé and Vini are two of the best strikers in the world today. They have big egos to score goals, become top scorers, and win individual trophies because they have the ability to do so. This will be Xabi's first job: to make Real Madrid play more collectively as a team, rather than individually.
Actually for next season too if Xabi can finally apply the same pattern as Zidane did where all the final results are focused on Mbappe for the finisher and their two wingers Vini, Rodrygo / Arda provide services like Bale and Benzema did in the Zidane era then everything will end well but indeed the problem that always occurs remains based on ego.
Vini's ego is getting bigger and bigger especially when he was one of the strong candidates for the Ballon d'Or before which makes it difficult for Madrid to improve.
There were moments when Vini seemed more active in his individual work and it was not uncommon for him to dribble until the opportunity was wasted because of his ego.
It's a task that could have been simple but in application it's not as simple as imagined, but if Xabi succeeds then he will have a considerable level of success in Madrid.
