Mackay-Steven, 24, has told the Daily Record how Deila has built a squad that can become great in the future.
“You could go through the squad,” the winger said. “Guys like Nir [Bitton], Stefan [Johansen], Jason [Denayer], Virgil [van Dijk], Stuart [Armstrong]. The spine of the team is really youthful and that is great going forward. We have a great nucleus of a squad here at good ages.
“It’s a talented bunch and we’re getting more and more familiar with each other’s style of play.”
It is impressive how youthful Celtic’s squad currently is, with even the elder statesman of Scott Brown yet to reach 30. Johansen and Leigh Griffiths are something of veterans being 24-years-old, whilst the Bhoys’ centre-back pairing consists of a 23-year-old, and a 19-year-old - admittedly one that is on loan.
Things bode well for Celtic’s future, and if head coach Deila is keen to stay in charge he will surely be able to start building a long-term legacy at the club.
Yet, this focus on the future has not taken away the demands of the present day, and after winning the League Cup earlier this term, there is still a potential treble to be claimed - with the young squad in the hunt for both Scottish Cup and Premiership.
It was a young team who showed their weaknesses in the early parts of the campaign, but have since grown into a fearsome collective. Although some key members of the squad will surely leave the club in the coming years, Deila has shown this term that he has all the nous about him to rebuild a dynasty using whatever tools he can get his hands on.
