Ronny Deila has admitted that he is a "little disappointed" with his Celtic team following the 2-0 Champions League win at home to Stjarnan on Wednesday.
The Bhoys drew first blood in the two-legged qualifier courtesy of goals in either half from Dedryck Boyata - who netted on his debut - and Stefan Johansen.
However, the Scots spurned a host of chances to effectively kill off the tie - including through Leigh Griffiths's penalty miss late on - and Deila says that he is not overly impressed with the result.
"Two-nil is a good result but I hoped we could finish them off. We had chances to win more but we were not effective enough," he told Celtic's official website.
"In the end, I'm a little bit disappointed that we didn't score more. But it's good we have a clean sheet and two goals to go on. We will have a good preparation for next Wednesday and we have a very good chance to make the next stage.
"We deserved to win but we could also have scored more. They also had one or two chances and it was good they didn't score. I'm happy but I'm not too excited."
Deila's men travel to Iceland for the conclusion next Wednesday.
