It was a case of mistaken identity at Paradise yesterday after Stuart Armstrong fired home his third goal of the season for Celtic.

Ronny Deila’s Bhoys took an early lead through Mackay-Steven but were pegged three minutes later by St Johnstone following some slack defending.

Two minutes before the half Armstrong put Celtic ahead and the win was wrapped up after Mackay-Steven found the net again from Stefan Johansen’s through ball.

It was the 23-year-old’s first goal since he hit a double against Inverness Caley Thistle and wasn’t going to give it up easily.

The on-rushing Armstrong lashed the ball home on the volley to seal the win for Celtic after met a brilliant cross from Mikael Lustig.

Celtic’s stadium announcer however had other ideas, as he credited the goal to Gary Mackay-Steven – who bagged his first two goals of the season.

Although he didn’t realise at the time, Armstrong wasn’t going to let his former Dundee United team-mate take it easily.

As quoted by the official Celtic website, he said:

I didn’t realise at the time. But he’d probably have taken it as well!

You could probably see the relief on my face when the ball went in. It’s just nice to be back playing well and winning games and being part of a good Celtic team right now.

Right now it’s back to basics and concentrating on what I can do to help the team. It’s about keeping calm, working on the things you need to work on and the performances will come.

At the business end of the season Celtic will need every player to step up when called upon and both Armstrong and Mackay-Steven have done that in recent games.
