Manchester United drew 1-1 at home against rivals Liverpool on Sunday afternoon, having led for a large chunk of the game.
But despite Marcus Rashford returning to goalscoring form, signing a proven goalscorer is still a priority for Ole Gunnar Solskjaer.
The United manager believes his squad is still short and says the club won't be afraid to spend in January.
“Of course, we're looking at one or two new signings," he told Sky Sports.
“We're one or two players light, and we've said that, but if the right ones are available in January then we might do something.
“January is a difficult window, anyway. But if there are players available and at the right price, I'm sure we will spend."
United were thought to have been looking at Juventus' Croatian forward Mario Mandzukic as a possible quick-fix.
The 33-year-old was reportedly the subject of United interest during the summer window and is believed to be available for £10m in January.
Werner has previously been linked to United's recent Premier League opponents Liverpool, with Jurgen Klopp reportedly a big fan.
He signed a new four-year deal at the start of this season, meaning he likely won't be cheap.
