"After leaving Barcelona, it was very important to Pep to join the right clubb, one that matched his own standards and aspirations, and Bayern are one of the best football addresses in the world game.
"I got to know Pep as a fairly straightforward kind of guy. He always demanded a lot of himself, especially at work. Although football isn't just his job, he loves it and he'll leave no stone unturned in the pursuit of success.
"We're close friends, he's a good bloke, tapped into his emotions and a family man. For all the success he's had, he's remained human."
