Stuart Armstrong has told the Glasgow Evening Times that Scott Brown and Charlie Mulgrew bring a lot to Celtic’s team.
The midfield pair are currently on the treatment table, although there are hopes that they could return before the end of the international break.
And Armstrong says that welcoming them back will be a big boost to Celtic’s squad, as they have missed the duo in their absence.
“We have a big squad and there are players who are versatile who can go in there,” Armstrong said. “But I don’t think there is any doubt that we miss Scott’s leadership qualities when he is out.
“I think any team would miss Scott Brown because he has a drive and an energy about him that definitely infiltrates the dressing room.
“It would be a great boost if he were to be fit in time for the game here against Ajax because he brings so much to the team, and the same goes for Charlie.
“They are big players who have huge experience at this level of the game and know what it takes to get a positive result.”
The Bhoys have already established a six-point lead at the top of the domestic standings, and they will be confident of making it past ninth-placed Kilmarnock.
Beating Ajax will be a tougher test, though, and Ronny Deila will be keen to have all of his players available for the fixture.
Celtic simply have to win the tie if they are to make it out of their Europa League group, meaning the pressure will be on for the match at Parkhead.
