Barry last month broke the all-time Premier League appearance record, previously held by Manchester United legend Ryan Giggs, when he made his 633rd career outing in the Baggies' 2-0 defeat at Arsenal.
“All the managers that I've worked under have had a slightly different take on things and Tony is no different," said Barry.
“I knew his style and the way he liked to play and I wasn't shocked by that. I've played against a lot of his teams.
“But the way he puts it across is something you learn and take on board.
“Tony really likes his teams set up nice and compact in a nice defensive shape, likes his team moving along in position.
“He takes things on to the training ground as he wants them on the pitch. Day by day I'm learning from him, but it's still early days."
