A positive weekend for the Hoops saw them extend their lead at the top of the Scottish Premiership.
A Tom Rogic screamer in the dying moments gave them a narrow victory over Kilmarnock last weekend, and the Hoops boss claimed that the mood around the team would have been much less positive had they gone into the break without securing the three points in their most recent encounter.
"It was so important to get the win before the international break," he told the Evening Times. "That would have been hard, to have gone in without it.
"But now we have a chance to get stronger. We have a lot of players away on international duty for the next few weeks and the guys who are not with their countries will get a bit of a break because we all need to prepare for the last chapter of the season."
As well as their own victory, the weekend became all the sweeter as their closest rivals in the Scottish Premiership title race, Aberdeen fell to a 2-1 defeat away to Motherwell, meaning that the Bhoys now hold a four-point lead at the top of the table and still boast a game in hand over the Dons.
The fact that Celtic could now have a seven-point advantage at the top by the time the split comes would surely be a huge boost to Deila's men as it will alleviate any of the pressure they may have been feeling, especially as they could have previously gone into the final fixture with Aberdeen knowing that a defeat may have seen Derek McInnes' side move above them.
However, they can go into the break knowing that they are now firmly in the driving seat, and a continuation of their recent results should see them bag another league crown.
