Once upon a time it was Scottish managers who were tearing up the English Premier League.

Kenny Dalglish, Graeme Souness, David Moyes. A certain Sir Alex Ferguson. All names who did magnificent things down south either as a player, boss or both.

Nowadays Mr Moyes is the last man standing in that regard, but it's our players that English clubs have finally started to notice.

Billy Gilmour is an elite youngster with tremendous potential at Chelsea. Andy Robertson is already a Premier League winner, with a Champions League medal also sitting in his trophy cabinet at home. John McGinn is - if you'll believe the hype in Birmingham - is a £50million player.

Then there's Kieran Tierney, Stuart Armstrong and Ryan Fraser. And there's more. But it's ex-Celtic man Tierney who former teammate Efe Ambrose believes is the man young hopeful players will look up to. Ambrose knows what KT is like having played alongside him in the Hoops' back four.

And the Nigerian former Hibs, Livingston and Derby County defender, who works in association with Premier Footballers, believes the success of Tierney and co in English football proves Scottish football provides a hefty conveyor belt of talent that perhaps doesn't always get the credit it deserves.

"Tierney went to Arsenal but there have been some great players who left Celtic like Virgil van Dijk, Stuart Armstrong," Ambrose revealed. "There's been a few of them who have left to go to England and have done well. What I would say is there is an opportunity for anyone down (in England) to know the league is competitive and it's good.

"They have good players who can play in the Premiership, Championship and League One so for me, enjoy the opportunity and the platform to show yourself. I believe Tierney has done it for the young ones, so many young players will aspire to be like Tierney which is going to help the league. It doesn't matter where you play, once you have that belief and work hard, they can do it."

Ambrose may not have played for Celtic since 2017 but he will always keep an eye on his former club. Having won six honours at Parkhead the 32-year-old will always have a soft spot for the outfit.

That's why it hurt the player last season when he watched rivals Rangers knock Celts about and stroll to their first Premiership title in 10 years. The problem for Ambrose is that he's not sure his old club will be able to turn things around and wrestle the trophy back again. 

It's going to be a tough season, he believes. But while he may not know too much about new manager Ange Postecoglou, Ambrose does know about the top tier in Scotland. And he knows how difficult the Australian could find it as Celtic manager. "It's not going to be an easy job looking at how Rangers are right now," Ambrose told AFTV presenter Charlene Smith. 

"The form of Rangers is going to be a huge responsibility. And a huge commitment from him to turn things around very quickly. The Celtic fans are impatient so just want results, so it's going to be a huge task for him."
