Danny Welbeck scored the only goal of a forgettable game as Arsenal booked a place in the Carabao Cup semi-finals at the expense of West Ham.
The pair had shared a goalless draw in their Premier League meeting at the London Stadium last week but this time out, with both sides fielding very different line-ups, it was Welbeck who made the difference to seal a 1-0 win.
The 27-year-old will not care how the goal came about as he got on the scoresheet for the first time since his double against Bournemouth on September 9.
