Celtic boss Ronny Deila has backed striker John Guidetti to rediscover his goalscoring form in the Scottish Premiership after going five games without netting.

The 21-year-old notched 11 goals in his first 12 appearances for the Bhoys in all competitions, but has failed to hit the back of the net since the end of November, including his side's 0-0 draw against Ross County on Saturday.

However, Deila is adamant that the striker, with a lot of hard work on the training pitch, will be able to fire in front of goal once more.

He told Sky Sports News: "He is struggling at the moment, you can see that. The only people who can do something about that is us so we have to work hard in training every day and see what we can do to get it going.

"We know that he can score goals, he has done it before. He hasn't become a bad player in a month. It is just small details that we are going to have to turn around.

"He will come back. My challenge, and his as well, will be to get that back as quickly as possible."

Celtic hold a five-point lead at the top of the Scottish Premiership from second-place Dundee United.
