"They were better than us tonight but our aim was to get through to Europa League and come third in the group, that would be a massive achievement and we did that".
He said: "The lads are a bit disappointed but things will come around once we realise we've achieved what we set off to do at the start of the group".
"There is vast pride but it is hard to feel that when you have lost".
The Parkhead manager admitted the result was a wake-up call for certain members of his squad as he said: "Some of our players have a long way to go before they can call themselves players at this level".
With neither side able to qualify for the knockout stages, at stake instead is a place in the Europa League, and he concedes he needs a lot of luck if the Scottish team are to miss out.
"It gives everyone a boost and we'll all be looking forward to it".
"But to overcome the three-goal difference to continue, everything has to be ideal and we also need all the luck in the world", he admitted.
The former Swansea and Liverpool boss moved to dampen down expectations regarding the Europa League.
"They deserved to be in the Europa League, they won 3-0 in Anderlecht, we won 1-0 tonight". There are going to be much, much better teams in there than ourselves.
"We were fourth seeds coming into this group and we've managed to finish third".
"You can say we're going to try to score in the first five minutes - and then you lose a goal in the first five minutes and it will be doubly hard".
Celtic fans chose to keep looking at the positives after the loss and made a decision to take to Twitter to heap the praise on Ntcham after an influential display in the midfield.
"We didn't need to score early but after 1-0 we didn't really get big chances for the second goal".
