I'm a new LFC fan and am going to get a jersey... which one should I get?

So I'm pretty new to soccer but have decided that after such a reviting World Cup that I want to get into Premier League soccer as well. Long story short, after a lot of going back and forth for quite some time, I decided that I wanted to be an LFC fan. Which brings me to my actual question...

My mother in law is going to London and Liverpool this week and wants to pick me up a jersey at the Liverpool One team shop, but I don't know who's jersey to get! I know that I am going to get a men's short sleeve home jersey, but I've been thinking about either Gerrard (obviously), Sturridge or Coutinho, but what are your thoughts? If you were getting a player's jersey, who's would you get and why? Thanks guys!
