Karetsas himself expressed optimism during a video recorded during a recent visit to his former club Genk, stating that all tests had returned negative and that he only needed to adjust to the intensity of the game.\n\nDortmund's sporting director Ole Buch noted that Karetsas had difficulty communicating while being taken off the field, as he was unable to speak at that moment. However, it is important to note that there were no prior warning signs of any circulatory issues preceding the incident.",
