CELTIC manager Ronny Deila was last night left angry and frustrated with his defenders and attackers after his side’s unexpected draw at Rugby Park.

The Norwegian was clearly unhappy with the way his side did not win a match they dominated for the most part and yet at the same time allowed Kilmarnock several chance of their own, two of which they took too end with a 2-2 draw.

Poor defending cost Celtic at both goals but just as worrying for Deila was the lack of clinical finishing at the other end, although Killie goalkeeper Jamie MacDonald performed superbly for the home side.

Deila said: “Everyone knows we were too sloppy defensively and also offensively as well. We have to be much more clinical when the chances come.

“I hope this was a one-off and we now have to bounce back against Inverness on Saturday. We need to learn from this.

“There were parts of the game in which we played good football. We have been excellent defensively and offensively for a long period of time, so this brought was back to reality a bit. We need to get back to the strategy we’ve always had.

“We should have scored a lot more than the two goals we managed.

“It wasn’t like to us. We wasted too much up-front after good play and we conceded the goals way too easily. Everything starts with good defence. That is what we have enjoyed so many good results up until now.

“I will see if we will make a lot of changes for the Inverness game.”

Deila paid tribute to Kilmarnock who after a rocky start in the game worked so hard for their draw.

They put Celtic under more pressure than any of their previous opponents, home and abroad, have done over the past six weeks.

He said: “They deserved their point. Kilmarnock created four or five good chances, which is more than we have had to deal with in a long time. So they did well.”

Nir Bitton scored a superb goal to make it 2-1 and it looked as if that would be the winner until Kilmarnock won a penalty at the end, converted quite brilliantly by Kallum Higginbotham.

Deila said: “It was superb goal and it’s something we want to see more of from Nir. He did well again.”

The fact Celtic dropped points a few days after John Collins made his now famous point about a lack of a test in Scottish football, although not once did the assistant manager said his side would always find things easy in the Ladbrokes Scottish Premiership, added a twist to the proceedings.

Deila said: “Nobody said it was going to be easy. We just need to get back on track on Saturday, that’s all.”

The Celtic manager would not confirm whether his club had or would make a bid for Scott Allan at Hibs or if Southampton were any closer to signing Virgil van Dijk.

He said: “There are 100 things that seem to be going on. Nothing has changed. I will only say when it someone comes in or leaves.”

Bitton came off in the game as did Kris Commons in the first-half and James Forrest, but all three should be fit for the weekend.

Kilmarnock manager Gary Locke was an understandably delighted man.

He said: “I know what John said but I don’t want to get involved in that. The only thing that mattered to me was getting a point for Killie. The players did really well to hang in and I was really proud of them.”
