Pjanic says Garcia has lifted his game.
"Since Rudi Garcia came here my game has been different to when I was at Lyon," he told Goal France.
"I have matured and have more experience, but it is also true that our style suits me more now. Garcia's teams rely heavily on the midfield, and he entrusts us to make the right decisions.
"I certainly have more responsibility now.
"I immediately understood why the Coach was signed when he arrived. Rudi spoke with the players straight away, and put trust in us immediately.
"The arrival of some experienced players calmed us down, and after a really good start, we got some genuine confidence."
