The Merseysiders are just two points above the relegation zone with a mere 18 goals from 17 matches and meet a City outfit who are flying high in third on the table.
Cahill knows the fans will be frustrated by the side’s lack of productivity in front of goal but insists that they will be working hard this weekend to achieve a positive result.
"The main thing is we are training well and our performances have been solid," Cahill told Sky Sports News. "It is frustrating as the fans know what we can do and what we can achieve, but if it does not hit the back of the net it means nothing.
“We are going to fight hard and make sure we are always in the trenches.
“This is a massive game. We love going to big stadiums and playing big teams like Manchester City. For us we relish the opportunity playing one of the biggest teams in the world at the moment. It is all for us to take."
"It is not anything I am interested in nor are any of the lads. Who knows what the situation really is. I respect the players' decisions and clubs and the best thing for us is to concentrate on our own game,” he added.
