The Leeds boss has been discussing his side's threat from out wide in the final third.
Indeed, Taylor recently netted a fabulous long strike and has been showing continual improvement going forward.
There are times when the 22-year-old is indisputably Leeds' biggest threat, while also holding up his end of the defensive side of things.
Stuart Dallas has impressed too, though, while Sam Byram has had his moments despite the ongoing saga that currently surrounds him. But United's German head coach wants both - as well as new signings Jordan Botaka & Will Buckley and midfielder Lewis Cook & Alex Mowatt - to emulate Taylor going forward.
Rosler is quoted as telling reporters by the YEP: "I can only encourage that sort of play Charlie Taylor has shown and I am very happy for him that he was on the scoresheet but we need more.
"We need that from Stuart Dallas, we need that from Sam Byram, we need that from (Jordan) Botaka, we need that from Will (Buckley), we need that from (Lewis) Cook, we need that from (Alex) Mowatt so I encourage my players to play more aggressively in the final third."
Leeds head into a tough clash against Middlesbrough on Sunday afternoon but the mood within the camp - as well as from fans - seems to be a positive one.
Rosler feels United can beat anyone on their given day and, even last season, the Whites proved as much with wins against the league leaders at the time on several occasions.
