Manchester United boss Erik ten Hag had a number of issues that required his immediate attention this summer, but perhaps the most pressing one of all was finding a way to solve the club's deep-rooted midfield problem.
That area of the pitch was neglected by the Dutchman's permanent predecessor, Ole Gunnar Solskjaer, who failed to acquire the No.6 that United have sorely needed for some time.
Unsurprisingly, Ten Hag made addressing that issue a priority. And although his ill-judged pursuit of Frenkie de Jong failed to bear fruit, the former Ajax chief made amends by prising Casemiro, one of Europe's elite defensive midfielders, away from Real Madrid.
