Mackay-Steven has still yet to win a professional trophy in his career.
Mackay-Steven said: “The last trophy I won was when I was around 14[-years-old] and at Thurso High. I was a runner up in the Scottish Cup with [Dundee] United, but it’s been a really long time, so it’s something I want to put right.
“I came here thinking there was a big chance of winning silverware, and the team has proved over the last few years that there is a winning mentality here.”
Mackay-Steven arrived at Parkhead on transfer deadline day from Dundee United, along with Stuart Armstrong, and the pair have played a key role in the Bhoys all-but clinching the Premiership title.
Ronny Deila’s men have won the League Cup since their arrival, but due to being cup tied they had to miss out on the action, and extend Mackay-Steven’s decade-long wait for a trophy.
When players move to Celtic, it is no surprise that they do it to guarantee the chance of winning silverware, and the Bhoys’ domination of Scottish football for their entire history speaks for itself.
They were just one game away from reaching the Scottish Cup final, with a potential treble on the cards, but Mackay-Steven will have to wait slightly longer for a trophy, with the Bhoys’ grasp on the Premiership trophy all-but secure.
