The most prominent current example is arguably former Hoffenheim attacker Roberto Firmino. He is an indispensable part of Jürgen Klopp’s Liverpool team, yet his goal involvements are way below those of teammates Sadio Mane and Mo Salah.

“When I think about Bobby I don't think about scoring,” Klopp once said of the Brazilian. “I think about how important he is. I'm not interested in that number [goals scored] because he is the connector for our team. He's so important for us.”

Sargent fulfils a similar role at Bremen. He excels at the metrics that are far less tangible: reading of the game, tactical awareness, positioning and tracking back.

"Josh’s absence really hurt us and it's the biggest compliment you can pay him, that you could really notice that he wasn't there," said Kohfeldt after Sargent missed Bremen’s Matchday 9 defeat by Wolfsburg last season.

"Josh is extremely important for our team," said Clemens Fritz, a former Bremen and Germany midfielder who now heads up the club's professional football department. "The amount of work he puts in, the stability he gives us in terms of defence - I've been really impressed by the way he's executing all that. We need that intensity. Josh is such an unbelievable team player.”
