Former Barcelona coach Pep Guardiola reportedly had Gerard Pique watched by a detective agency when he was dating Shakira.
El Cofidencial says Guardiola employed the detective agency Metodo 3 to follow the centre-back, before and during the early days of his relationship with pop singer Shakira.
A source, a former employee of Barca, is quoted saying that Guardiola and [director of external relations Manel] Estiarte did not hesitate in using the detective agency if they suspected a player was leading an unhealthy lifestyle.
Guardiola was "obsessed" with his players' personal lives, which is consistent with previous reports of him clashing with Pique over his public relationship and personal activities with Shakira. But the investigation into Pique's love life apparently didn't turn up much.
