He’ll be disappointed that he maybe didn’t get three goals this evening, second one he should slot away, but wonderful skill and ability for the first goal and he was tireless all evening pressing the ball and posing a threat.' Sportsmail columnist Jamie Carragher said Sterling would learn from the last six to 12 months at Liverpool . Sportsmail columnist Jamie Carragher said on Sky Sports: 'There’s no doubt over the last six to 12 months, in years to come he’ll look back over this period now as a massive learning curve for him. 'When you’re a 20-year-old kid, you make mistakes at that age, I did, I’m sure we all do. It’s just important that he learns from it because Raheem Sterling, for how good a footballer he is, he needs to be on the back pages, not the front pages and that’s a problem for him in these last few months.'
