Manchester United traveled to Liverpool last weekend to take on their fierce rivals and left Anfield with a goalless draw - the first time they’ve drawn a blank this season.
United followed it up with a narrow 1-0 win over Benfica in midweek - and many have criticised Jose Mourinho for parking the bus in the last two games.
But Smalling, whose side have scored 21 in eight games so far, reckons few sides will stop United from scoring this term.
"You can see that we have attacking players, albeit they still have to defend when Liverpool have those attacks," Smalling told Sky Sports ahead of today's game at Huddersfield.
"But we kept it tight and we know that when we get those chances, more often than not, when we keep a clean sheet or are defensively sound, then nine times out of 10 we will win that game because not many teams can stop us from scoring.
"More often than not, we are the team that is on the front foot, because we are the one with the ball and we have to keep passing it side to side and finish them.
"And more often than not, when we get a goal and go 1-0 up and then the other team has to come out, that is often when we score the second, the third and the fourth.
“And we have killed teams in the last 20 minutes. But the onus is on us to have to break those teams down."
