Gerard Pique revealed that his relationship with Pep Guardiola changed after he started dating Shakira.
"We reached a moment of tension with him, not just me but the dressing room in general," Pique told La Sotana on Monday.
"The rivalry with Jose Mourinho [at Real Madrid] wore us down a lot. Pep wanted absolute control over everything that was happening.
"I started dating Shakira and our relationship changed. Now, the relationship is perfect. But there was a lot of pressure on me then. I felt like I had to do everything in training perfectly.
"If there was a moment I thought about leaving Barca, it was that [2011-12] season. I struggled in that last season with Guardiola."
