Meslier was only a teenager when he became the Leeds number 1 towards the end of their promotion campaign in the Championship and has remained the first choice since then.
Bielsa never lost faith in him once he broke into the line-up and played a key role in his development until being sacked by Leeds last year.
Meslier conceded that being a goalkeeper in a Bielsa side was very hard given the way the team played their football and it inevitably exposed him to more shots on his goal because of how open they were.
But he stressed that Marsch is more defensive and wants his side to play on the counter-attack more.
Meslier told French sports daily L’Equipe: “With Marcelo, it was difficult because it was total football with individual marking.
“Nobody was doing that. We felt like the ultimate team, we were the only ones playing that style of game.
“Afterwards, inevitably, it exposed me a lot as soon as there was someone who escaped his marking.
“I was being peppered with shots a lot.
“Jesse is more defensive than Bielsa.
“We play on the counter-press, he asks us to go quickly on the counter-attack.”
With Hugo Lloris announcing his international retirement, many expect Meslier to now break into the France squad.
