London - Manchester United manager Louis van Gaal was rewarded for a bold change of tactics as his team came from behind to beat Preston North End 3-1 in the FA Cup fifth round on Monday.
A turgid first-half display in which United dominated possession against their third-tier opponents but failed to create a single clear scoring chance forced Van Gaal to act.
A goal behind following Scott Laird's 47th-minute strike, the Dutchman hauled off misfiring Colombian forward Radamel Falcao, replacing him with winger Ashley Young and pushing Marouane Fellaini further forward.
