The 22-year old Swedish striker, who is on a season-long loan from Manchester City, has not netted for the Hoops since November after a bright beginning to his temporary spell in Glasgow.
Guidetti slotted home nine goals in his first eight outings for Celtic but has not registered in his last 10 outings for the Scottish champions, however, Deila is not getting too worried.
"It is not about goals, it is about winning and doing the job for the team and he does that perfectly well and the goals will come as a consequence of that," said the Bhoys boss.
"I was delighted with his performance against Partick (Thistle on Wednesday). He was working for the team, he was a team player. So he has to stop thinking about results and start thinking about processes.
"Why do I score goals? Why am I not scoring goals? Instead of 'I have to score goals' because then they won't come.
"You have seen many good strikers who haven't scored for a while. We knew there was going to be a dip and now he is into it and it is how he works himself out of it.
"He is on the right way and he will get his results if he keeps on doing it, and he will improve as a player and be back on a better level. I think he will realise that we will make him a better player.
"This environment is very good for young players who want to get better and hopefully he will stay here."
