Ronny Deila expects Stefan Scepovic to "go on to score more goals" after breaking his duck in Celtic's 2-1 Europa League win over Romanian outfit Astra Giurgiu at Parkhead last night.

The 24-year-old Serbian striker had failed to hit the net in his first six appearances for the Hoops after signing from Sporting Gijon for a reported £2.3million in the summer.

Scepovic was only playing in the Group D fixture because on-loan striker John Guidetti was not registered in time for the group stages of the competition, and he did little to win over already sceptical Celtic fans when he missed two sitters with his head early in the second half as the Scottish champion struggled.

However, his persistence paid off in the 73rd minute when he headed in an Anthony Stokes free-kick before celebrating with as much relief as joy.

Midfielder Stefan Johansen made it 2-0, only for Gabriel Enache to pull a goal back but it ended with Celtic at the top of the section on seven points with Salzburg ahead of the trip to Romania for the return game on 6 November.

Manager Deila was especially pleased to see Scepovic get his first goal and believes there is more to come.

The Norwegian said: "He was very tense before the game, I could see it in him and there was a big relief, of course, when he scored.

"But I know what a goalscorer he is and it is not the last goal we will see from him.

"We know what he has. He is always in front of goal and smelling chances.

"I see in training that he is good on the ball and scores goals. He really wants to perform for this club. You can imagine what you feel when you score your first goal.

"He will become more confident as well. I see in training that he is good on the ball and scores goals so I am very happy for him."

Deila believes 10 points could be enough to qualify through to the knockout stages but insists there is still a long way to go.

He said: "I am taking nothing for granted. It is a lot of hard work in Europe, with two away games to go and there are some very even games.

"So we need to be at our best if we are to go through.

"We gave Astra some chances in the first half with some bad passes and some stupid mistakes. We were too slow and took too many touches on the ball.

"When we got to 2-0 I hoped the game was over but they came back again and that was disappointing. But in the end we won the game and in the second half we had more chances."
