The most expensive signing was Nkunku, who cost €37m plus bonuses. Just two summers earlier, the Blues had budgeted a €100m investment: €65m immediately to RB Leipzig to bring the striker to the Premier League, and another €35m if they won the Champions League in the following three years. In truth though he struggled to establish himself: 18 goals in 62 total matches were not considered enough. A move to Milan a-la-Pulisic followed, but his time has been bumpy so far.
