West Bromwich Albion boss Steve Clarke admits he treasured his time at Chelsea with Jose Mourinho.
Clarke was grateful to Mourinho for the way he welcomed him into the fold during his first time in charge.
"I had it in the back of my mind that I would do it at some stage," he told the Daily Mail, "and I was at Chelsea - a club I loved with a job I loved, in charge of the youth team.
"Then Jose arrives. I'm presented with a choice. Do I stay as I am? Or take the risk to join him and his group, to work with a guy I didn't know and a group I didn't know?
"I knew I was the token Chelsea man. Sat there with my sweatshirt with the Chelsea badge on it and Chelsea scarf around my neck. It could have been a failure. I could have been kicked out with them. But that was the big step for me. I thought: 'Let's go and make a career of this'.
"They made me feel welcome. There were five Portuguese and me. If they did hold a conversation, one of them would always explain it, they made a big effort.
"As a coach, Jose was super-meticulous. Every session planned. I never went into a session not knowing what he wanted out of it. The players got the same messages.
"It was a great education. I was in charge of the youth team. Jose had just won the Champions League. I'm a quiet person. Suddenly, I'm working with a man who is super-confident.
"He changed the mindset of that club. Having said that, the team was growing. It had grown under Claudio (Ranieri)."
