There are few jobs in professional sports that are more important, and more unforgiving, than that of coach. Their most significant work is invisible to the fans. When things go wrong, the coach is usually the first to be blamed. When the team is enjoying success, it is the players that typically reap the accolades.

Coaches can make or break a club. They can transform mid-tier teams to genuine contenders, and they can utterly “lose the locker room”.

But the weight of responsibility that many coaches feel is not just the expectation to win. It’s the cultivation of a winning culture — creating the kind of environment that encourages players to sacrifice for one another, and strengthening the bonds that enabling them to withstand the dangers of failure and success.
