The young playmaker has struggled to consistently reproduce his best form in the Premier League, prompting scrutiny over his adaptation.
Wirtz, who rose rapidly at Bayer Leverkusen with 18 goals and a Player of the Season award during their unbeaten domestic double in 2023–24, has found life more challenging in England following his big-money summer transfer.
Speaking during the international break, Nagelsmann expressed frustration with the growing narrative around the 22-year-old, stressing that the backlash has been excessive.
"That was a completely normal situation that affects a young player. He’s someone with emotions and first has to deal with facing criticism. At that intensity, it wasn’t justified," he said.
"We grew even closer, had many good conversations where he really opened up. He’s intelligent and very open, and you get a lot back from talking to him.
"He can take a lot from this phase and come out stronger.”
