The question for Arsenal is how much of Emery’s squad truly needs reshaping, and how much one man — a £45m centre-half, say — could transform the players around him. The best evidence of what happens when it goes well is at Liverpool, where the presence of Virgil van Dijk has allowed Andrew Robertson to become the best left-back on the continent and Joel Matip to suddenly become capable of spraying 50-yard passes despite having a Lionel Messi lodged in his pocket.
