Gerrard was joining Swansea City midfielder Darren Pratley in telling their team mates to keep their calm in the first derby clash of the season at the Liberty Stadium on Saturday lunchtime.
Speaking to BBC Wales Sport, Gerrard said “If you get all pumped up then you are more than likely to do something stupid which is not good”
Whilst Pratley – a scorer the last time the two sides met at the Liberty added “You need to keep your heads in a big game. Obviously the atmosphere’s going to be good.
“I think the team that keeps their concentration and keeps their heads are the team that come out on top.”
Gerrard also believes that the jeering of him and his team mates will help Cardiff and he added “Of course it is going to be hostile
“They are not going to give us applause because we are their bitter rivals and it will be the same when the Swans come to the Cardiff City Stadium, as they will get a hostile atmosphere which is good.
“But when we get booed and jeered it gives us a boost and gives us a ‘we want to get a result’ kind of mentality.
“Yet we have got to keep our head and discipline as we will have less of a chance to win the game with 10 men.
“We have to think it is just another game as it is just another three points, but it is more than that to the supporters as they want the bragging rights over their rivals.”
