Goals from Robin van Persie and Nemanja Vidic put the Premier League leaders in charge, before Daniel Sturridge pulled one back for the Reds.
With Rodgers regularly picking Joe Allen and Lucas Leiva in midfield, it has been suggested Liverpool lack the power in midfield to compete against the top sides.
But the 40-year-old rubbished such claims, insisting there is plenty of “fight” in his squad, encapsulated by Liverpool’s tenacious captain Steven Gerrard.
“Aggression isn’t about having a 6ft 3ins player in the middle of the field who is going to drive you forward, aggression is in the mind,” says Rodgers.
“We have Steven Gerrard, who is one of the best examples of that in this country over the last 10 years. We have that aggression but it is not about what size you are, it is about the fight which is in there.
“In the second half the ability to fight was much better and we were much more aggressive in our play and attitude and we should have got something.”
