Zlatan Ibrahimovic and Sergio Aguero have made stunning starts for Manchester United and Manchester City respectively so far this season.
The Swede was on target in United's 3-1 opening day victory at Bournemouth and netted a double against Southampton on Friday Night Football.
Aguero has also hit the ground running, scoring three goals in two Premier League games against Sunderland and Stoke.
Asked who would have the bigger impact this season, the Sunday Supplement panel of journalists had mixed reactions.
Jonathan Northcroft of the Sunday Times said the pair will be trying to outscore each other.
"They are going to be scoring almost in opposition to each other," Northcroft said. "Ibrahimovic was asked about the Golden Boot after the game and he brushed it off but you know he would absolutely love it.
"Aguero’s completely revived by Guardiola...He looks maybe half a yard quicker as well. And I’m amazed at Ibrahimovic's physical condition for a bloke that turns 35 next month."
Mirror journalist John Cross said the Argentine would score more than the United striker but predicted the 34-year-old's impact would go beyond the pitch.
"I think Ibrahimovic’s big influence has been his influence, his sheer presence," Cross said. "Even his post-match interviews and the way he was joking with Pogba, it just changes the atmosphere around Old Trafford."
Jason Burt of the Telegraph said: "On the pitch I think it will be Aguero and I think there is so much more to come from City. The early signs are fabulous.
"But off the pitch, Zlatan Ibrahimovic will for Man United. I just think his sheer presence, his arrival has made such a statement for Man United"
