Kieran Tierney’s breakthrough into the first-team is partially down to the help Emilio Izaguirre gave the youngster.
That’s according to the young defender himself, who is quickly becoming the master at and starter at left-back.
The 18-year-old has gone from the apprentice to the master in just a few years, and Izaguirre is the unfortunate one to lose his place.
His performances against Aberdeen, Fenerbahce and Molde – some of Celtic’s biggest games this season are extraordinary. He is faultless, composed and most importantly, he knows what the fans want – as he is a Hoops fan himself.
For a young player to consistently perform in the biggest games, says a lot about Tierney and those who helped with his development.

Tierney believes the man he replaced, Izaguirre, was part of that development.
As quoted by the Scotsman, Tierney said:
Emilio Izaguirre helps me a lot, especially given he plays in the same position. It’s a good team full of professionals.
Emilio’s played at the World Cup so obviously anything he says I’ll take on board.
He’s absolutely brilliant with me and it hasn’t just been the last few weeks or even this season. It’s been over the last year as well. He’s taken me under his wing, given me tips and I’m extremely grateful for that.
Tierney also praised Celtic captain Scott Brown for his input and help along the way.
Scott Brown’s been amazing with me too. Scott’s obviously done everything as captain of his club and country, so he gives me tips what to do at various times.
The young star also summed up his own development and the crazy pace at which he’s developed. It seems like he is still trying to wrap his head around it all.
It’s been nuts, the progress I’ve made.
My experiences recently with Celtic have definitely helped me push on. I’ve played in big games, top of the table clashes and Europa League games. That can only be a positive.
