Terry lifted Chelsea's first two Premier League titles following Mourinho's arrival at the Stamford Bridge club in 2004, with a third arriving in 2015 after his return as Blues boss.
“The best manager and coach I worked with was Mourinho," declared Terry to Sky Sports. “He was the first one to come in and revolutionise things at Chelsea.
“You would come in at 8am and he would be the one setting the cones out. He was out there in the pouring rain, getting his session ready.
“He would have four grids of the pitch and we would move from that one to that one and between each one there were drinks. We would train for an hour and we would move from there, to there to there.
“He brought three young kids in as ball-boys and every time the ball went out of play, another one came back in instantly. If there was a bad pass or a bad role from one of his staff, he went berserk and it was embarrassing for them. His standards were so high. From the players, his medical team, he was on everything.
“His attention to detail was incredible and he changed the way I thought about football. The first session when he came in and at the end of it, the lads thought, wow that was a session.
“Mentally and psychologically, he had us from day one. We bought in to whatever he was going to deliver that day and he was the same when he came back. Having his presence there was enough. He had his eyes on everyone and when he speaks no one messes about or plays with a ball. You listen to him, he was the boss.
“I would give everything for him. I would leave that pitch in a coffin for him and every player felt the same."
