The England striker added to his goalscoring run with another strike during the 5-0 win over Group E's whipping boys.
The strike continued the former Manchester United's hot streak of goalscoring run for club and country, having found the net 7 times in his last 8 games, surely making Louis van Gaal's remarks about him lacking the goalscoring capability of the likes of Robin van Persie and England teammate Wayne Rooney harder to swallow.
Welbeck performed well in the centre forward position for England against the European minnows, and his willingness to work hard for the ball up front continues to be one of his greatest strengths for both his club and country.
One area that he could continue to work at is his decisiveness and effectiveness in front of goal, with more than a couple of goalscoring opportunities drifting away in the admittedly crammed San Marino penalty box.
Early in the second half, Welbeck finally got the goal he had been waiting for. The 23-year-old was the benefactor of good work down the wing from Arsenal teammate Alex Oxlade-Chamberlain, before superbly dispatching the ball inside the near post.
On top of his goal, Welbeck had two other shots on goal, one attempt missed after Rooney flicked on a corner and another shot saved from the right side of the area after good work from Gunners fullback in Kieran Gibbs
Welbeck was tenacious in his defensive work upfront as he always is, conceding two fouls as he harried the San Marino defence.
But with neither the Arsenal man or his former United strike partner Wayne Rooney putting the visitors to the sword like they would have surely been hoping to, it looks like the form Welbeck displayed against Galatasaray recently is something that will have be cultivated rather than come naturally.
