The mid 2010s were an interesting era for Celtic for sure. It would be safe to say that the Rangers were nowhere near challenging for the league title at that point in time. In fact, it was in the 2016/17 campaign that they made it to the top flight. With no real challengers, it is safe to say that the Hoops had some pretty uninspiring campaigns.
Ronny Deila's run as Celtic manager is certainly one that will not go down as one of the most exciting in the club's history. And some of the signings from this era did not spend a long time at Parkhead after Brendan Rodgers arrived in 2016.
Gary Mackay-Steven is someone who Celtic signed while Deila was the manager of the club. He was brought in from Dundee United.
Mackay-Steven was clearly rated highly by Deila and he played a decent bit of football for Celtic under his management. But after a single season in the Rodgers era, he headed for the exit door and joined Aberdeen.

Mackay-Steven has had a decent career since leaving Celtic. He has played for Aberdeen and Hearts, and even had a spell in the MLS with New York City FC, a lot of it under the management of Deila.
He now finds himself at another Scottish club. As reported by BBC, Kilmarnock have announced the signing of Mackay-Steven on a short-term deal until the winter break.
Let's see how things turn out for him there. He is still just 33 years of age. While Mackay-Steven did not play a lot of football for Celtic, he did contribute to the club while he was at Parkhead. So, we can only wish him the best of luck in his new journey at Kilmarnock.
