Liverpool's defence has been their Achilles' heel for years, so Jurgen Klopp deserves huge credit for transforming them into the most stingy team in the Premier League this season.
Although he is known as an attack-minded manager who throws caution to the wind, Klopp has proved himself to be a man of tactical acumen. He had adapted his team to be more defensively conscious, turning them into a better-rounded side capable of challenging for that elusive league title. They lead Manchester City by four points at the top of the table after 21 games.
Standing at the precipice of history, Klopp has placed his faith in the players who have got him here.
