Kelvin Wilson spent two years at Celtic and won three trophies.
It barely took him two minutes to learn just how big a club it really is.
The Englishman had spent time in the Championship down south with the likes of Nottingham Forest and Preston North End but it was not until his Glasgow stint where he discovered what a massive club really is like.
It remains difficult for the 39-year-old to explain to doubters or cynics the expectations at Parkhead or the demands of the fanbase.
Scottish football has forever been disrespected and disregarded by the more arrogant of English pundits as well as fans of even the smaller Premier League sides.
But Wilson has never shared that view.
If anything, all his time in Scotland did was prove to him just how big the Hoops are as an entity and global brand.
Wilson even recalls one afternoon in particular which proved he’d taken a gargantuan step up after a win in the Scottish Premiership was treated like a defeat.
Kelvin Wilson gets frustrated at explaining how big a football club Celtic is
Since that day he knew what to expect and how to handle it and he has found it tough to explain that to anyone who needs told just what Celtic is like as a culture.
Speaking to The Celtic Way, Wilson said: “It gets frustrating trying to explain to people just how big Celtic are as an entity and a club.

“I was thinking ‘Wait a minute, we’ve won the game’ but that was not enough.
What Wilson said about his time in the Glasgow ‘goldfish bowl’
“The difference between just winning the game and playing ‘The Celtic Way’ was a massive thing for both the fans and media alike.
“The whole goldfish bowl of Glasgow was another thing that was a new experience for me. I keep myself to myself and I have a very low social media profile as that’s the way I like it.
“I don’t thrive off attention that way and that was a massive shock to the system.
“Going for meals was difficult as fans would always want to talk and I totally understand that as I was a football supporter too growing up and some people just get starstruck at times.
“It took a bit of getting used to, let me tell you.
