Trent Alexander Arnold believes that his career will not end in Liverpool, and it's a good thing that he has been learning Spanish for a while. Some fans are just unbelievable. Real Madrid has been interested in the player for some years, and no player has ever rejected an offer from them. As everybody understands Arnold will not leave Liverpool if it is not for Real Madrid.
In my opinion, it is really bad if a player cannot speak any language except his own. Football players need to learn multiple languages because many players today struggle to understand English unless it is translated for them. Arnold wanted to join Real Madrid without working with some interpreters, as we can see he speaks Spanish perfectly.
Believe or not, Trent knew that his career has been changed in two or three latest seasons when opponents knew more about his defensive weakness and aimed at exploiting it as much as they can. He lack of solid defensive contributions for his teams from Liverpool to England national team. Both Southgate, Klopp and Slot realized about it and they used Trent more regularly in the midfield or an attacking player in order to take advantage of Trent's great skills in passing and distant shots.
Real Madrid is a club with tradition of attacking and throughout its club history, it has many star players at wings like Roberto Carlos and Marcelo. They possibly are expecting good contributions of Trent more at wings than in the midfield but Xabi Alonso is cleverly and he will not what to do for maximizing performances of Trent in Real Madrid.
