Joe Allen was the late hero for Stoke City as his close range finish ensured the troubled Potters left Old Trafford with a share of the spoils.
Zlatan Ibrahimovic, Paul Pogba and Jesse Lingard all had chances to break the deadlock for a dominant Manchester United in the first half but were unable to find the net due to Stoke goalkeeper Lee Grant and their profligacy.
United's pressure eventually told on 69 minutes when substitute Martial fired home a loose ball from inside the penalty area to give his profligate team-mates the lead they deserved, but they were pegged back 12 minutes later by Joe Allen, who tapped home from close range.
