Former Manchester United midfielder Park Ji-Sung believes he was a regular under Sir Alex Ferguson because of the trust the manager had in him and his high-energy performances.
The former South Korea international made over 200 appearances for the Red Devils and was often deployed in the club's big matches.
The 26-year-old, speaking to MUTV about the club's latest documentary, Park: Past, Present & Future, believes his high-octane performances saw the manager keep faith with him.
'Maybe one of my strengths was to bring the energy to the team,' he said.
