Callum McGregor insists this Celtic team can evolve further. 

In what is a worrying thought for most of the Premiership, the Hoops skipper reckons there's more to come from the current Scottish champions.

Ange Postecoglou's men restored their nine-point gap at the summit of the table with a 1-0 win at Pittodrie on Saturday.

The fit-again Celtic skipper struck a matter of minutes from time to shatter Aberdeen.

The Hoops were heading for a 0-0 draw after a glut of missed chances in the north east.

This could've given fuel to Rangers in their bid to recover the title race.

However, McGregor, returning to the team after a two month lay off with a knee injury, rifled home from the edge of the box past Kelle Roos.

It was the 200th goal of Postecoglou's tenure at the club. And CalMac says there's more to come from the squad.

He said: “That’s over the space of 18 months, which is a really good return.

“It’s just important we keep evolving as a team, always looking after the defensive side of the game. But it’s a good record to have.

“We have put ourselves in a good position and it’s always about us.

“We can only look after our fixtures, we can’t worry about what is happening anywhere else.

“If you prepare, turn up and win your games, then you are in a good place.

“It’s important mentally to stay strong and that is what we are about.”

On his comeback goal itself, it was a moment that the Scotland international had dreamt of. 

He added: "It’s brilliant — I couldn’t have dreamt it any better than that.

“Coming up here is always a difficult venue. You have to be strong, physically and mentally.

“It was good to be back on the pitch to help the team and the manager.

“We showed great character to keep going right to the end.

“We dominated the game for large spells and just missed that wee bit of luck or quality. To keep going shows the type of team we want to be.

“Aberdeen gave us space around the box and we were trying to probe and find space to shoot.

“To be fair, they defended the box pretty well, but it’s testament to the boys that we just kept going.

“I feel good now. We had a good week in Portugal and I feel fine.”
