Matt O'Riley insists most in football can't even begin to imagine what it's like to play for Celtic... with respect.

The 23-year-old scored his first goal for Brighton at the weekend as they defeated Manchester City 2-1 in the Premier League.

It's been a slow start to life on the south coast for the Danish international after a horror injury put him out of action for the first few months of his Brighton career.

Speaking to Seagulls legend Glenn Murray on the club's official podcast this week, the £25m player made it clear the stark differences between playing for his new employer, and the Scottish Premiership champions.

"Respectfully, the pressures of playing at Celtic are for most people unimaginable," he said. "It is not easy to win every game of football regardless of who you are playing against.

"If you have 11 men behind the ball who are well-organised sometimes it is difficult to score. The longer the game goes on, the anxiety builds up in the crowd.

"And you just need to learn to be able to accept that but also just somehow block it out and stay focused.

"To do that every single game is really tiring, you know - mentally and physically - to sustain it as well.

Anyone who is able to play at Celtic for a long time, like James Forrest and Callum McGregor, to have that kind of relentless mentality... it is genuinely tiring.

"I have so much respect for them to do it over and over again, 60 games a season.

"I was so aware that whatever I did on the pitch contributed to so many fans' happiness. They are so mad up there.

"To the point that I know when they're at their daily jobs they are having banter with their Rangers pals all week if the result isn't good.

"I think for me as a player in terms of preparation to go somewhere else it is perfect just because the demand is so high. I really enjoyed the pressure of it, though, the responsibility of it. You really test your limits every single week, you've got to do it again and again and be better.

"If you don't then they'll let you know about it, the fans. It is only because they care so much. In that sense, that is why you don't take it personally. They just care about their team doing well."

Asked if he misses Celtic, he responded: "Yeah, a little bit. I miss the people, I think the people are really friendly up there, I grew up down south in London so I know what the people are like but people up north are super friendly which is quite nice."
