Ronny Deila has heaped praise on Craig Gordon following his performance in Celtic's 1-0 victory over Dinamo Zagreb on Thursday.

The Scottish champions collected all three points in the Europa League clash thanks to an early Kris Commons goal, but Deila was keen to stress the importance of Gordon's contribution.

"Craig was unbelievable," the Norwegian told reporters. "I said to him in the dressing room that we have him to thank for conceding zero goals and winning the game.

"He was a prospect to come in before I was the manager of the club, but I knew he was a fantastic goalkeeper, who was out for a long time.

"He can't do much better than he has shown. He can work on his kicking but he is a fantastic keeper and very calm."

Gordon joined Celtic on a free transfer in the summer.
