Known for his intense personal style of coaching, current Manchester City boss Pep Guardiola famously left Barcelona because he felt drained and had nothing left to give, and in a recent interview, admitted that he doesn't see himself coaching for very much longer.
Guardiola is an extremely demanding coach, and what he expects from his players he also does of himself, which has meant that the Sky Blues man sees the finish line in sight.
"My coaching career is nearing its end," he told NBC. "I won't be coaching at 60 or 65.
"At Manchester City, I'll be here for three years or maybe longer, but I'm now approaching the end of my career as a manager - I'm sure of it."
