The boss was speaking at a pre-match press conference ahead of Monday's clash with Kilmarnock.
But the Norwegian still maintains that the club's biggest priority is to keep their existing stars.
"Hopefully we’ll have a good January transfer window and we’ll be strong going into the second part of the league," Deila told reporters.
"Our aim is to keep the players here so we have consistency and to get in players who will make the squad better."
On Celtic's league form, Deila gave a fair assessment of the Bhoys' season so far... 'good - but could be better.'
“It’s in our hands,” the Celtic boss added. “If we win all our games we’ll be champions and that’s what we want to do.
“We’re in a good position – we could be better but, then again, we could be worse – so it’s in our hands, we’re in every competition and we’re looking forward to it.
“We have a lot of experience of this because we’re always challenging for the championship, and we’re only concerned about ourselves."
Meanwhile, Deila also provided an injury update ahead of Celtic's SPL clash with Kilmarnock:
