What is the device that Alexander-Arnold wore in Liverpool training and what is it for?

In a final, like the Champions League (Saturday, May 28 at 2:00 p.m., Peruvian time), the details can make the difference. So, as part of the preparation for Real Madrid vs. Liverpool, Jürgen Klopp used the tools that worked best for him throughout the season and one of them could be seen during the training of the first team.

In last Wednesday’s rehearsal, Trent Alexander-Arnold and Kostas Tsimikas were the center of attention for the press that attended the ‘Reds’ day. Both players wore devices on their bodies and heads that are called brain sensors. Immediately the curiosity arose to know what the function is.

According to information from The Sun newspaper, these instruments help improve player performance in specific areas of the game. This technology used by Liverpool is of German origin and the electrodes that are connected to the cases that the soccer players wear on their heads help to collect data from the brain.

For example, with the information obtained, athletes can adjust actions such as hitting the ball and, from there, plans are put together to carry out personalized activities. Specifically in the case of Alexander-Arnold, the striker has the chance to fine-tune the crosses he launches from the wings or the set pieces he executes.

There are more details about the device from the company Neuro11, owned by German neuroscientist Dr. Niklas Hausler and his business partner Patrick Hantschke, in terms of achieving maximum concentration and an optimal state of mind to face key moments, such as in Paris in the fight for the ‘Orejona’.

“Step by step we try to refine it so that in the end the player has a mental tool so that it doesn’t matter if it’s a free kick in training or a free kick in the 93rd minute of the Champions League final. You know what to focus on and you don’t get disoriented”Hausler explained in an interview for The Athletic media.
