Former Celtic defender Andreas Hinkel has fond memories of all of his previous managers during his spell at Parkhead.
Celtic and another one of his old clubs Stuttgart go head to head at Parkhead tonight in the first leg of the Europa League knockout phase play-off.
Hinkel spent three and a half years at Celtic between 2008-2011, winning a league title and a League Cup and played under three different managers – Gordon Strachan, Tony Mowbray and Neill Lennon.
"I think Gordon Strachan did a great job," he told BBC Scotland.
"He signed me and I spent this time together with him. I had the chance to get to know Tommy Burns as well – a huge Celtic legend – he passed away at this time, so it was very emotional this period as well, I experienced a lot.
"The first year was really special, to win the title. It was quite tight against Rangers but we made it at the end. All the Old Firm games, all the international games – Europa League, Champions League were really special and I have really good memories.
"Of course you always have bad things as well, like changes in the manager position but I think that is normal. I think Tony Mowbray was a really good guy, he had a good philosophy and it didn't work out really well with the team, it can happen, but he was a good manager as well.
"And Neil Lennon is a guy who gives everything, he motivates the team he wants you to leave everything on the pitch.
"So I took something out of every manager I had there."
