Pep Guardiola has revealed his toughest critic at Bayern Munich is his wife. In an interview for the car manufacturer Audi, the Spanish manager joked that he talked to his wife about his selection policy and that she often took issue with it.

"My wife Cristina sometimes complains about my game tactics," said Guardiola. "She tells me I should start with the same team that won last time. Trying to explain my principle of squad rotation to her is harder than telling Arjen Robben: 'You'll be sitting on the bench today.'"

Guardiola also admitted in the interview that his decision to leave Barcelona and take a year's sabbatical from the game was prompted by Chelsea's Champions League semi-final victory over the club in 2012.

"We were much better than our opponents, but then conceded an unnecessary goal in the return leg, and before we knew it we were out of the competition," said Guardiola. "That was a really tough defeat for me. I felt like I could no longer reach my team."

Asked if that defeat was what convinced him to resign from the club, Guardiola replied: "Yes. If you can no longer reach your players, as a coach, the time has come to move on."

Elsewhere in the interview, Guardiola confessed that he and his children have a shared love of Coldplay. Meanwhile, Bayern Munich will go into Friday's Champions League quarter-final draw and the manager will be hoping not to be pitted against Chelsea, just in case another defeat leads to a similar sort of rush of blood to the head as the one that convinced him to retire from Barcelona.
