When it comes to turning great players into great coaches, we need to learn from the Italians. Let's take a look at Antonio Conte - a captain and leader of Juventus in his playing days who, like Gerrard, always wanted to be a coach. After retiring as a player, Conte started his new career as an assistant manager in Siena, his first head coaching job was Arezzo in serie B, then Bari, Atalanta, and Siena again, this time as a head coach. By the time he was appointed a manager of Juve, he had 6 years of experience working with smaller teams. It was not all a smooth ride: he got fired after his first season in Seria B and got relegated, abused by fans and fired after his first season in Serie A.
He led Juve to a scudetto in his first season in charge and is now considered a savior by fans - but would he have made it this far if he was thrown in the deep end of the pool before he learned to swim and then got his confidence and reputation destroyed at the very beginning of his career? Juve have benefitted from a system that allowed their former captain to learn the coaching trade away from the spotlight and brought him back to the club when he was 100% ready for the job. Now they have the best of both worlds: an iconic player who is loved by fans and understands the soul and traditions of the club, but also a good tactically savvy modern coach. Now that's a real dream scenario.
By the way in Italy every coach has complete rigorous training and pass an examination at a special school for coaches in Coverciano. This kind of system is why Italians keep managing the best teams in England while English managers could not collectively produce a single top 3 finish in England in the last 10 years (amazing, isn't it?). There is nothing more stupid than turning over the most important job in a big club to a complete novice just because he was a good player. So I wish Gerrard every success when he hangs up his boots and tries himself at managing, but there is no question that he should prove himself by managing other teams before we can even start the conversation about managing Liverpool.
