Celtic 0-0 Ross County: Deila says Guidetti goals will return
Manager Ronny Deila is backing John Guidetti to return to form after the Celtic striker drew another blank in the home 0-0 draw with Ross County.
Having scored 11 goals in 10 games, the 22-year-old has now gone five matches without a goal.
"We know that he can score goals, he has done it before," said Deila.
"He hasn't become a bad player in a month. It is just small details that we are going to have to turn around. It is just small details to work on."
The draw has stretched the champions' lead at the top of the Scottish Premiership to five points over Dundee United and Aberdeen, with the latter playing Inverness in their game in hand on Sunday.
Celtic substitute Callum McGregor and Ross County's Filip Kiss both hit the woodwork but clear-cut chances, especially for the dominant home side, were few and far between.
"We had the ball for 90 minutes but we didn't manage to break them down," added Deila, who hopes the calf knock which forced forward Anthony Stokes off early in the game is just a "small thing".
"We had so much possession we had to create more and that is what is disappointing.
"We have opened a lot of teams and created a lot of chances but this time we didn't do it. That was the most disappointing part."
Despite gaining a hard-fought point, Ross County dropped to the bottom of the table after being leapfrogged by St Mirren.
However, "mindful" that Celtic had won 5-0 in Dingwall earlier in the season, Staggies boss Jim McIntyre said: "I am delighted. The players carried out the game plan very well.
"The last time against Celtic we tried to have a go and took a hammering so that was in the mind-set today.
"We had to be hard to beat and break down and they carried that our very well.
"I think it's important when you come to Parkhead that you grow into the game. At Dingwall we lost two goals in 12 minutes and Celtic have great quality so we were mindful of that fact.
"And the only result we could affect today was our own and we take the positives out of taking a point at Parkhead.
"I don't think many teams will come here and do that. St Mirren's results are irrelevant to us, we can only concentrate on ourselves.
"Is it (dropping a place) disappointing? Of course it is, but I'm really pleased with what we've done today.
"The thing that's been letting us down is not winning games, but we haven't been taking a hammering off teams.
"It's been the odd goal here and there and we have to turn that to the odd goal in our favour."
