In the summer, FC Porto showed interest in the German U-20 national goalkeeper Tjark Ernst. However, since Porto's coveted first-choice goalkeeper Diogo Costa ultimately stayed, no concrete offer was made for Ernst.

According to information from the Portuguese newspaper "A Bola", FC Porto is interested in Hertha's goalkeeper Tjark Ernst (21, contract until 2026). Ernst, who had a stable debut season as number 1, is considered a candidate if Diogo Costa leaves. Hertha wants to extend with the U-20 national goalkeeper. However, if a club - like AC Florenz did with Berlin's former number 1, Oliver Christensen, last year - were to make a serious move, a departure is possible.
