Ange Postecoglou claimed Celtic were only showing the building blocks of what they can achieve after a comfortable 2-0 win at Motherwell.

Postecoglou praised his side's "outstanding goals" after Jota finished well following an incisive through ball from Socceroo Tom Rogic, and David Turnbull swerved a long-range effort into the top corner past a bemused Liam Kelly.

Celtic cut the gap on Scottish Premiership leaders Rangers to four points with the top half of the table wide open and Postecoglou believes his side will go from strength to strength.

"We are just beginning," Postecoglou said. "Whatever we are doing now, I know we will be better moving forward.

"We are just beginning to see the foundation of what we are trying to build.

"That doesn't excuse us not winning games of football and not being in a better position and the mistakes we have made.

"But that for me is the reality - I know that we will be a much better team as the season goes on and players get even more understanding and belief in what we are trying to do.

"That's not taking anything away from this performance, it was a really strong performance."
