WHY DO LIVERPOOL NEED ADAM?

i mean adam is a very raw in your face player u never know what will happen when he's on the field. gerrard is always getting injured and is not that good of a midfield striker and dead ball specialist as he was 2 years ago so charlie adam would be good but i think suarez is good enough to take free kicks they have enough players for that but he would be a great addition to the squad for the cheap price that is rumored around 5 million
