Julen Lopetegui insists he knows exactly what he has taken.
In a video posted on the club's official Twitter feed, Lopetegui said: "Coming back at the manager of the first team is a tremendous feeling. It requires responsibility, but it is also very exciting and emotional."I know that I am joining the best and the most demanding club in the world and I am convinced that I can meet these high expectations. Now we'll start preparing for our first trophy, the UEFA Super Cup on August 15."
