Ange Postecoglou has urged his Celtic players to keep up their level of performance with the Parkhead injury woes easing.

Jota and Callum McGregor made the difference to see off Aberdeen, with Lewis Ferguson's penalty proving to be a consolation for the visitors.

Celtic move back into second spot in the Premiership table and keep the pressure up on league leaders Rangers.

However, the threadbare Parkhead squad has been pushed to its limits heading into the clash with the Dons just days after facing Bayer Leverkusen.

The Australian has called for his squad to continue to continue to develop after a positive injury update going into a jam-packed December fixture list.

Ahead of Thursday's clash with Hearts, Postecoglou told Celtic TV: "Hopefully Nir (Bitton) should be available again and Tommy Rogic will definitely be available for Thursday. Carl Starflet isn't too far away, Greg Taylor isn't too far away, so we are getting some troops back.

"It's a heavy schedule and we don''t want out level of performance to drop."

Having been left disappointed by the club's Europa League exit at the hands of Bayer Leverkusen, the Celtic boss was pleased to see his side bounce back from the disappointment with a hard-fought three points.

He said: "It was an important three points.

"It was a bit of a danger game for us because we put so much into it on Thursday, emotionally and physically. We were disappointed at the end of it and you have to back up and put in a performance.

"It's a tough opponent. They worked hard and were well organised. In the first half we didn't dominate as much as we would have liked, in terms of creating opportunities, but in the second half I thought we were really on it.

"It was as much about showing what we are about as anything else. After a big European game you can go in feeling a bit flat, but we really put a big emphasis on it. Cal (Callum McGregor) was driving them all game.

"We had to find different ways to break them down and creating chances. It was good to see that we went through a couple of avenues today. "
