Ronny Deila has admitted that he was tempted to ring the changes at half-time during the 3-0 win over Inverness Caley Thistle.
Celtic were fortunate to go in at the interval on level terms with the highland side looking more likely to break the deadlock.
Goals from Gary Mackay-Steven and Leigh Griffiths before the hour mark turned the match around with substitutes Scott Allan, Ryan Christie and Patrick Roberts having a major impact in the final third of the match.
“I could have (made changes at the break) but maybe we wouldn’t have won the game,” Deila suggested. “ It is hard to say. Every team comes from solid defence first of all, that is the first thing. If you are open then there are problems.
“We have a very hard-working team. Maybe there is not so much creativity in the starting eleven but you know that they are going to do the hard work and that is important, and it is also good that we have players who can come on like today. Then we need to get this together, the hard work and the flair.”
Looking at the impact of the substitutes Deila added: They have skills that can open defences and take people on and they showed that today and that is very positive.
“They had energy and looked like they really wanted to show themselves and I think I would expect that when they come at Celtic Park.
“When you are 2-0 up it is a different ball game. There is more space but in the end we won as a team and that is a positive thing but they played with the confidence and worked hard and that is the combination I am looking for.”
