Sir Alex Ferguson is hoping Javier Hernandez's winner against Stoke could ignite Manchester United's season.
Mexican Hernandez, in action because of Wayne Rooney's injury, also scored a fine header in a dramatic 2-1 victory.
"He has good instinct and knows where the goal is," said United boss Ferguson after his stuttering side secured their first away league win of the campaign.
"We have some important games up until Christmas. We have to make our mark in the league. Hopefully we can kick on."
It was a wonderful performance from Hernandez, who helped to ensure a happier end to a difficult week for his 68-year-old manager having seen his top striker Rooney eventually sign a new five-year contract.
With Chelsea extending their lead at the Premier League summit on Saturday, United headed to the Britannia Stadium having drawn their previous four away fixtures.

But the Mexican striker's two goals proved the perfect tonic for Ferguson with an astonishing backward header in the first half and a late strike which cut short Stoke's celebrations when Tuncay came off the bench to equalise on 85 minutes.
"When their goal went in you start to say to yourself it is going to be one of those seasons, but Chicharito came up with the winner," added Ferguson, referring to Hernandez by his nickname.
"The supporters reaction was fantastic to the goal and our players reaction was fantastic. It is the kind of goal United score over the years. A late goal met by incredible enthusiasm by the fans. They knew it was an important one."
The win moved United third, five points behind Chelsea, while the 22-year-old Hernandez has now scored four goals in his last five appearances since signing in July.
Hernandez delighted with double
"Hernandez deserves this. He works so hard and you get rewards for that," United defender Gary Neville told BBC Sport.
"He's tough and he's got the right attributes. His work rate and attitude is phenomenal. He's one of the most exciting young prospects we've seen at the club for some time."
Neville had been lucky to stay on the pitch in his 600th game for United following a challenge on Matthew Etherington three minutes before the interval.
With the former England right-back having already been booked, Stoke boss Tony Pulis was furious with referee Andre Marriner's decision not to show the red card.
"If it was a Stoke City player at Old Trafford and he committed those two fouls, would he have been sent off?" asked Pulis.
