From the moment that Erik ten Hag was first linked with the Manchester United job, speculation soared over who'd cut it for the Dutch tactician.
Could Cristiano Ronaldo press? Will Bruno Fernandes be tidier on the ball? Is Harry Maguire still the man to be captain? But perhaps the most long-standing issue which Ten Hag was faced with was whether or not to stick with David De Gea, the Red Devils' No.1 goalkeeper for more than a decade.
A four-time Player of the Year coming off the back of a resurgent season between the posts, his super saves still couldn't hide his obvious deficiencies with his feet. Unable to play out from the back comfortably, a tenet of Ten Hag's philosophy, the 31-year-old had a fight on his hands to convince his new boss of his capacity to adapt - particularly after being on the end of a scolding during United's pre-season tour.
