What a crazyness to see a guy with 37 years being champion of football..... as a coach. I mean he is younger than most of us, and he is most younger than a lot of active footballers, i super crazy to see this kind of things, for example Cristiano Ronaldo is 4 years more older than him.
Congratulations to him anyways.
What we've become accustomed to is older managers. I'm against this. Young managers with footballing intelligence can also achieve success. We can give Xabi as an example. Despite his age, he won the Bundesliga championship and reached the Europa League final. He also had a very good playing career. This means he has a good technical understanding of these matters. He's currently managing Real Madrid and could achieve success again at a young age.
In someway i agree with you but i also dont know if is 100% correct the statement about young coachs, the main thing aside of tactics on modern football is the thing of control the behavior and feelings of the players, the psicological part is today more important than a lot of others and young guys maybe cant have all the background necesary to knew what they have to do.
