Wirtz and Juliane — today a professional footballer for Werder Bremen in the Frauen-Bundesliga — were just 18 months apart in age and would play against each other in cages around the campsite or join games with other children.

Importantly, Liverpool’s amortisation costs remain relatively modest. The cost of Wirtz’s transfer — plus agent fees — spreads out to around £21.8 million per season. Combined with Jeremie Frimpong’s signing, Liverpool’s amortisation increases, but still lags behind Chelsea, City, and others.
