Ralf Rangnick is a coach who demands that every one of his players fully buys into his footballing philosophy. You're either on board with his hard-running, hard-pressing style, or you're history.
So as the German arrives at Old Trafford to serve as Manchester United's interim manager, it hasn't taken long for stories to appear linking the club to Amadou Haidara.
Haidara is very much Rangnick's man, having played for both Red Bull Salzburg and then their German sister club RB Leipzig.

The 23-year-old midfielder understands what Rangnick requires of his players and his skillset neatly fits the style of football we're imminently about to see at United.
